section and the
Pagination
section
k
Based on the information provided in the knowledge sources, I can help you configure the Incremental Sync and Pagination sections for your custom connector using the Airbyte Connector Builder UI. Let's break it down into two parts: 1. Incremental Sync: For the Incremental Sync section, you'll need to use the DatetimeBasedCursor configuration. Here's how you can set it up: - Set the "Cursor field" to the field in your API response that represents the last updated or created timestamp. - Choose the appropriate "Datetime format" that matches your API's timestamp format. - Set the "Start datetime" to "user input" to allow the user to specify the initial sync start time. - Set the "End datetime" to "now" to fetch all data up to the current time. - For injecting the start and end timestamps, you'll need to use custom parameter injection: - Disable the default "Inject start/end time into outgoing HTTP request" options. - Instead, use the generic parameter section at the bottom of the stream configuration form to set up your
start_timestamp
and
end_timestamp
parameters. [Incremental sync | Airbyte Documentation](https://docs.airbyte.com/connector-development/connector-builder-ui/incremental-sync#custom-parameter-injection) provides more details on custom parameter injection. 2. Pagination: For the Pagination section, you'll need to use the Cursor Pagination method. Here's how to configure it: - Select "Cursor" as the pagination method. - In the "Cursor value" section, choose where the cursor is located in the API response (typically in the response body or headers). - Specify the property that holds the cursor value (e.g., "next_token" or similar). - Configure how to inject the cursor into the next API request. This is usually done as a query parameter, but check your API documentation for the exact method. - Set the stop condition to when no cursor value is returned or when it's an empty string. [Pagination | Airbyte Documentation](https://docs.airbyte.com/connector-development/connector-builder-ui/pagination#cursor-pagination) provides more details on configuring cursor pagination. Remember to test your configuration thoroughly to ensure it works correctly with your specific API. If you encounter any issues or need more specific guidance, you may need to consult your API's documentation or consider using the low-code CDK or Python CDK for more complex scenarios.

@kapa.ai what's the format that represents timestamp?
k
A message from kapa.ai
To answer your question about the format that represents timestamps in Airbyte's custom connector configuration, I'll refer to the information provided in the knowledge sources. According to the [YAML Reference documentation](https://docs.airbyte.com/connector-development/config-based/understanding-the-yaml-file/reference#/definitions/DatetimeBasedCursor), Airbyte supports various datetime formats for representing timestamps. Here are some of the commonly used formats: 1. `%Y-%m-%dT%H:%M:%S.%f%z`: This format represents a full ISO 8601 timestamp with microsecond precision and timezone offset. Example:
2023-04-15T07:30:58.962074+00:00
2. `%Y-%m-%dT%H:%M:%S%z`: Similar to the above, but without microsecond precision. Example:
2023-04-15T07:30:58+00:00
3. `%Y-%m-%d`: This format represents just the date. Example:
2023-04-15
4. `%s`: Unix timestamp (seconds since epoch). Example:
1686218963
5. `%ms`: Unix timestamp in milliseconds. Example:
1686218963123
6. `%s_as_float`: Unix timestamp as a float with microsecond precision. Example:
1686218963.123456
When configuring your custom connector, you should choose the format that matches the timestamp format used by your API. If your API uses a different format, you can combine these placeholders to create a custom format string that matches your needs. For example, if your API returns timestamps in the format "YYYY-MM-DD HHMMSS", you would use the format string
%Y-%m-%d %H:%M:%S
. Remember to set this format in the "Datetime format" field of the Incremental Sync configuration in the Connector Builder UI.

@kapa.ai airbyte no stream slices were found, likely because the parent stream is empty.
k
A message from kapa.ai
This error message suggests an issue with stream slicing in Airbyte, specifically related to a parent-child stream relationship. Let's explore this problem based on the information from our knowledge sources. The error "no stream slices were found, likely because the parent stream is empty" typically occurs when you're working with nested or dependent streams, and the parent stream doesn't return any data. This can happen for several reasons: 1. The parent stream genuinely has no data. 2. There's an issue with the configuration of the parent stream. 3. There might be a problem with the stream slicing logic. To address this issue, you can try the following steps: 1. Check the parent stream: Make sure the parent stream is correctly configured and is able to retrieve data. You can do this by running a sync for just the parent stream and verifying that it returns records. 2. Review your stream slicing configuration: If you're using a custom implementation of stream slicing, review your
stream_slices()
method. According to the [Stream Slices documentation](https://docs.airbyte.com/connector-development/cdk-python/stream-slices), this method should return a list of dictionaries, where each dictionary describes a slice. 3. Verify the parent-child relationship: Ensure that the child stream is correctly referencing the parent stream and that the slicing logic is properly implemented. 4. Check for any recent changes: If this error started occurring after a recent change, review those changes to see if they affected the stream slicing or parent-child stream relationship. 5. Implement proper error handling: As shown in the [check and error handling documentation](https://docs.airbyte.com/connector-development/tutorials/custom-python-connector/check-and-error-handling), you can implement better error handling to provide more informative messages when issues like this occur. If you're using a low-code or YAML-based connector, you might need to review your configuration to ensure that the parent stream is properly defined and that any necessary parameters for slicing are correctly set. For more detailed debugging, you may need to examine the full error logs and possibly the source code of your connector. If you're using a community or pre-built connector, you might want to check the Airbyte GitHub repository or community forums for similar issues or open a new issue if it's a potential bug. Remember, without more specific details about your connector and configuration, it's challenging to provide a more precise solution. If you need further assistance, please provide more information about your specific setup, including the connector type, configuration details, and any relevant code snippets.

A message from kapa.ai
Thank you for providing more details about your code. After reviewing the code snippets you've shared, I can see that you're working with a custom implementation of stream slicing for parent and child streams. Let's analyze the potential issues and suggest some solutions. 1. Parent-Child Relationship: Your
ChildStreamMixin
class is trying to use the parent stream's
_conference_slices
, but it's not clear how this relationship is established. Make sure that the parent stream (likely
Conferences
) is properly linked to the child streams (
RecurringConferences
and
AssociatedSessions
). 2. Stream Slices Initialization: In the
stream_slices
method of
ChildStreamMixin
, you're trying to access
self.parents
, but this attribute is not defined in the provided code. Ensure that
self.parents
is properly initialized with the parent streams. 3. Caching Mechanism: You're using a caching mechanism with the
use_cache
property, which is good. However, make sure that the cache is being populated correctly before it's accessed. 4. Error Handling: Add proper error handling and logging to help identify where exactly the issue occurs. Here's a suggested modification for your
stream_slices
method in `ChildStreamMixin`:
Copy code
python
def stream_slices(
    self,
    sync_mode: SyncMode,
    **kwargs,
) -> Iterable[Optional[Mapping[str, Any]]]:
    combined_conference_slices = []

    if not hasattr(self, 'parents') or not self.parents:
        self.logger.error("No parent streams defined for this child stream.")
        return []

    for parent_stream in self.parents.values():
        conference_slices = parent_stream._conference_slices
        if not conference_slices:
            <http://self.logger.info|self.logger.info>(f"Fetching conference slices for parent stream: {parent_stream.__class__.__name__}")
            list(parent_stream.stream_slices(sync_mode=SyncMode.full_refresh, **kwargs))
            conference_slices = parent_stream._conference_slices

        if not conference_slices:
            self.logger.warning(f"No conference slices found for parent stream: {parent_stream.__class__.__name__}")
        else:
            combined_conference_slices.extend(conference_slices)

    if not combined_conference_slices:
        self.logger.error("No stream slices were found, likely because all parent streams are empty.")
        return []

    for conference in combined_conference_slices:
        self.is_finished = conference["conference_id"] == combined_conference_slices[-1]["conference_id"]
        yield conference
This modification includes better error handling and logging, which should help you identify why no stream slices are being found. Additionally, ensure that your parent streams (
Conferences
) are correctly populating the
_conference_slices
list in their
parse_response
method.

Conferences
) are correctly populating the
_conference_slices
list in their
parse_response
method. If you're still encountering issues, you might want to add more logging statements throughout your code to track the flow of data and identify where exactly the process is failing. For example, add logging in the
parse_response
methods of both parent and child streams to confirm that data is being processed and slices are being created. If the issue persists, you may need to debug the parent stream (
Conferences
) to ensure it's actually returning data and populating the
_conference_slices
list. Check your API connection, authentication, and any parameters being passed to ensure you're requesting the correct data. [Airbyte CDK Python Documentation](https://docs.airbyte.com/connector-development/cdk-python/) provides more information on stream slicing and parent-child stream relationships, which might be helpful for further troubleshooting.

Thank you for providing more details about your code. After reviewing the additional information, I can see that you're working with a custom implementation of parent-child streams for a BigMarker API integration. Let's analyze the potential issues and suggest some solutions. 1. Parent-Child Relationship: The parent-child relationship is established in the
SourceBigMarker.streams()
method. This looks correct, but there might be an issue with how the child streams are accessing the parent stream's data. 2. Stream Slices Initialization: In the
stream_slices
method of
ChildStreamMixin
, you're trying to access
self.parents
, which is correctly set in the
SourceBigMarker.streams()
method. However, there might be an issue with how you're accessing the parent stream's slices. 3. Caching Mechanism: You're using a caching mechanism with the
use_cache
property, which is good. However, there might be an issue with how the cache is being populated or accessed. Here are some suggestions to resolve the "no stream slices were found" issue: 1. Debug the parent stream: Add logging statements in the
Conferences
class, especially in the
parse_response
method, to ensure that
_conference_slices
is being populated:
Copy code
python
   def parse_response(self, response: requests.Response, **kwargs) -> Iterable[Mapping]:
       self._conference_slices = []
       for conference in super().parse_response(response, **kwargs):
           slice = {"conference_id": conference["id"], "conference_type": conference["type"], "recorded": conference["recorded"]}
           self._conference_slices.append(slice)
           <http://self.logger.info|self.logger.info>(f"Added conference slice: {slice}")
           yield conference
       <http://self.logger.info|self.logger.info>(f"Total conference slices: {len(self._conference_slices)}")
2. Modify the
stream_slices
method in `ChildStreamMixin`: Update the method to handle potential errors and add more logging: ```python def stream_slices(self, sync_mode: SyncMode, **kwargs) -> Iterable[Optional[Mapping[str, Any]]]: combined_conference_slices = [] self.logger.info(f"Parents: {self.parents.keys()}") for k, v in self.parents.items(): self.logger.info(f"Processing parent stream: {k}") conference_slices = v._conference_slices if not conference_slices: self.logger.info(f"No conference slices found for {k}, fetching...") list(v.stream_slices(sync_mode=SyncMode.full_refresh, **kwargs)) conference_slices = v._conference_slices self.logger.info(f"Conference slices for {k}: {len(conference_slices)}") combined_conference_slices.extend(conference_slices) self.logger.info(f"Total combined conference slices: {len(combined_conference_slices)}") if not combined_conference_slices: self.logger.error("No stream slices were found, all parent streams are empty.") return []

is being populated:
Copy code
python    def parse_response(self, response: requests.Response, **kwargs) -> Iterable[Mapping]:        self._conference_slices = []        for conference in super().parse_response(response, **kwargs):            slice = {"conference_id": conference["id"], "conference_type": conference["type"], "recorded": conference["recorded"]}            self._conference_slices.append(slice)            <http://self.logger.info|self.logger.info>(f"Added conference slice: {slice}")            yield conference        <http://self.logger.info|self.logger.info>(f"Total conference slices: {len(self._conference_slices)}")
2. Modify the
stream_slices
method in `ChildStreamMixin`: Update the method to handle potential errors and add more logging:
Copy code
python    def stream_slices(self, sync_mode: SyncMode, **kwargs) -> Iterable[Optional[Mapping[str, Any]]]:        combined_conference_slices = []         <http://self.logger.info|self.logger.info>(f"Parents: {self.parents.keys()}")         for k, v in self.parents.items():            <http://self.logger.info|self.logger.info>(f"Processing parent stream: {k}")            conference_slices = v._conference_slices            if not conference_slices:                <http://self.logger.info|self.logger.info>(f"No conference slices found for {k}, fetching...")                list(v.stream_slices(sync_mode=SyncMode.full_refresh, **kwargs))                conference_slices = v._conference_slices                        <http://self.logger.info|self.logger.info>(f"Conference slices for {k}: {len(conference_slices)}")            combined_conference_slices.extend(conference_slices)         <http://self.logger.info|self.logger.info>(f"Total combined conference slices: {len(combined_conference_slices)}")         if not combined_conference_slices:            self.logger.error("No stream slices were found, all parent streams are empty.")            return []         for conference in combined_conference_slices:            self.is_finished = conference["conference_id"] == combined_conference_slices[-1]["conference_id"]            yield conference
3. Ensure proper initialization: In the
SourceBigMarker.streams()
method, make sure that the parent streams are fully initialized before being passed to child streams. You might want to add a method to force the initialization of the parent stream's slices:
Copy code
python    def initialize_parent_slices(self, parent_stream):        list(parent_stream.stream_slices(SyncMode.full_refresh))
Then call this method before creating child streams:
Copy code
python    conferences = Conferences(**args)    self.initialize_parent_slices(conferences)    recurring_conferences = RecurringConferences(**{"parent": conferences, "parents": {"conferences": conferences}, **args})
4. Check API responses: Ensure that the API is returning the expected data. Add logging in the
BigMarkerStream
class (which I assume is the base class for all your streams) to log the raw API responses:
Copy code
python    def parse_response(self, response: requests.Response, **kwargs) -> Iterable[Mapping]:        <http://self.logger.info|self.logger.info>(f"Raw API response: {response.text[:1000]}...")  # Log first 1000 characters        # Your existing parsing logic here
5. Verify authentication: Double-check that your
BigMarkerAuthenticator
is working correctly and that you're able to make successful API calls. After implementing these changes, run your connector in debug mode to get more detailed logs. This should help you identify where exactly the process is failing and why no stream slices are being found. If you're still encountering issues after these modifications, you may need to review the BigMarker API documentation to ensure that you're making the correct API calls and parsing the responses correctly. Also, consider reaching out to BigMarker's support if you suspect there might be an issue with the API itself. [Airbyte CDK Python Documentation](https://docs.airbyte.com/connector-development/cdk-python/) provides more information on stream slicing and parent-child stream relationships, which might be helpful for further troubleshooting.
Thank you for providing more details about your code. After analyzing the code snippets, I can see a few potential issues that might be causing the "no stream slices were found" error. Let's go through them: 1. Parent-Child Relationship: In the

ChildStreamMixin
is using these relationships. 2. Stream Slices Initialization: In the
stream_slices
method of
ChildStreamMixin
, you're trying to access
self.parents
, which is correct based on how you've set it up in
SourceBigMarker
. However, there's an issue in how you're handling the slices. 3. Caching Mechanism: You're using a caching mechanism with the
use_cache
property, which is good. However, the cache (
_conference_slices
) is being reset in each

def stream_slices(
    self,
    sync_mode: SyncMode,
    **kwargs,
) -> Iterable[Optional[Mapping[str, Any]]]:
    combined_conference_slices = []

    for parent_stream in self.parents.values():
        conference_slices = parent_stream._conference_slices
        if not conference_slices:
            # This line is incorrect, as it's calling its own stream_slices method
            # all(super().stream_slices(SyncMode.full_refresh, **kwargs))
            # Instead, call the parent stream's stream_slices method
            list(parent_stream.stream_slices(sync_mode=SyncMode.full_refresh, **kwargs))
            conference_slices = parent_stream._conference_slices
        combined_conference_slices.extend(conference_slices)

    if not combined_conference_slices:
        self.logger.error("No stream slices were found, likely because all parent streams are empty.")
        return []

    for conference in combined_conference_slices:
        self.is_finished = conference["conference_id"] == combined_conference_slices[-1]["conference_id"]
        yield conference
2. Modify the
parse_response
method in
Conferences
class:
Copy code
python
def parse_response(self, response: requests.Response, **kwargs) -> Iterable[Mapping]:
    # Don't reset _conference_slices here, as it will clear previously cached slices
    # self._conference_slices = []
    for conference in super().parse_response(response, **kwargs):
        slice = {"conference_id": conference["id"], "conference_type": conference["type"], "recorded": conference["recorded"]}
        if slice not in self._conference_slices:
            self._conference_slices.append(slice)
        yield conference
3. Add logging statements to help debug: ```python import logging logger = logging.getLogger("airbyte")

python def parse_response(self, response: requests.Response, **kwargs) -> Iterable[Mapping]:     # Don't reset _conference_slices here, as it will clear previously cached slices     # self._conference_slices = []     for conference in super().parse_response(response, **kwargs):         slice = {"conference_id": conference["id"], "conference_type": conference["type"], "recorded": conference["recorded"]}         if slice not in self._conference_slices:             self._conference_slices.append(slice)         yield conference
3. Add logging statements to help debug:
Copy code
python import logging  logger = logging.getLogger("airbyte")  class ChildStreamMixin:     def stream_slices(self, sync_mode: SyncMode, **kwargs) -> Iterable[Optional[Mapping[str, Any]]]:         <http://logger.info|logger.info>(f"Generating stream slices for {self.__class__.__name__}")         # ... (rest of the method)  class Conferences(BigMarkerStream):     def parse_response(self, response: requests.Response, **kwargs) -> Iterable[Mapping]:         <http://logger.info|logger.info>(f"Parsing response for Conferences, current slice count: {len(self._conference_slices)}")         # ... (rest of the method)
4. Ensure that the
BigMarkerStream
class (which is not provided in your code snippets) is correctly implementing the
stream_slices
method and other necessary methods. 5. In the
SourceBigMarker
class, add a check to ensure that the parent streams are returning data:
Copy code
python def streams(self, config: Mapping[str, Any]) -> List[Stream]:     # ... (existing code)     conferences = Conferences(**args)     test_slices = list(conferences.stream_slices(sync_mode=SyncMode.full_refresh))     if not test_slices:         logger.warning("Conferences stream returned no slices. This may cause issues with child streams.")     # ... (rest of the method)
These changes should help address the "no stream slices were found" error. The main issues were likely the incorrect calling of
super().stream_slices()
in the
ChildStreamMixin
and the resetting of
_conference_slices
in each
parse_response
call. If you're still encountering issues after making these changes, you may need to debug further by adding more logging statements and checking the API responses to ensure you're receiving the expected data. [Airbyte CDK Python Documentation](https://docs.airbyte.com/connector-development/cdk-python/) provides more information on stream slicing and parent-child stream relationships, which might be helpful for further troubleshooting. </assistant_answer>

@kapa.ai estou usando o cdk mas não estou achando o HttpAuthenticator
k
A message from kapa.ai
Entendo que você está usando o CDK do Airbyte e não está encontrando o HttpAuthenticator. Vou tentar ajudá-lo com base nas informações disponíveis. O HttpAuthenticator que você está procurando provavelmente foi substituído por classes de autenticação mais específicas no CDK do Airbyte. Aqui estão algumas opções que você pode usar para autenticação HTTP: 1. BasicHttpAuthenticator: Para autenticação básica HTTP usando nome de usuário e senha. 2. TokenAuthenticator: Para autenticação baseada em token. 3. OAuth2Authenticator: Para autenticação OAuth 2.0. 4. BearerAuthenticator: Para autenticação usando um token Bearer. 5. ApiKeyAuthenticator: Para autenticação usando uma chave de API. Você pode importar essas classes do módulo
airbyte_cdk.sources.streams.http.auth
. Por exemplo:
Copy code
python from airbyte_cdk.sources.streams.http.auth import BasicHttpAuthenticator, TokenAuthenticator, OAuth2Authenticator
Se você precisar de uma implementação de autenticação personalizada, você pode criar sua própria classe herdando de
HttpAuthenticator
. Por exemplo:
Copy code
python from airbyte_cdk.sources.streams.http.auth import HttpAuthenticator  class CustomAuthenticator(HttpAuthenticator):     def __init__(self, auth_header: str, auth_token: str):         self.auth_header = auth_header         self.auth_token = auth_token      def get_auth_header(self) -> Mapping[str, Any]:         return {self.auth_header: self.auth_token}
Se você estiver tendo problemas específicos com a autenticação ou precisar de mais orientações, por favor, forneça mais detalhes sobre o tipo de autenticação que você está tentando implementar. Para mais informações sobre autenticação no CDK do Airbyte, você pode consultar a [documentação oficial do Airbyte sobre autenticação](https://docs.airbyte.com/connector-development/cdk-python/http-streams#authentication).

@kapa.ai não achei ApiKeyAuthenticator
k
A message from kapa.ai
Entendo que você não encontrou o
ApiKeyAuthenticator
. Peço desculpas pela confusão. Vou esclarecer a situação com base nas informações mais recentes disponíveis na documentação do Airbyte. O
ApiKeyAuthenticator
não é uma classe diretamente disponível no CDK do Airbyte como mencionei anteriormente. Na verdade, para autenticação com chave de API, você pode usar a classe
TokenAuthenticator
. Aqui está como você pode fazer isso: 1. Importe o `TokenAuthenticator`:
Copy code
python from airbyte_cdk.sources.streams.http.auth import TokenAuthenticator
2. Crie uma instância do
TokenAuthenticator
com sua chave de API:
Copy code
python auth = TokenAuthenticator(token="sua_chave_de_api", auth_method="ApiKey", auth_header="Nome-Do-Header")
Onde: -
token
é sua chave de API -
auth_method
é definido como "ApiKey" -
auth_header
é o nome do cabeçalho que a API espera para a chave de API (por exemplo, "X-API-Key") Se você precisar de uma implementação mais personalizada, você pode criar sua própria classe de autenticação. Por exemplo:
Copy code
python from airbyte_cdk.sources.streams.http.auth import HttpAuthenticator  class CustomApiKeyAuthenticator(HttpAuthenticator):     def __init__(self, api_key: str):         self.api_key = api_key      def get_auth_header(self) -> Mapping[str, Any]:         return {"X-API-Key": self.api_key}
Para mais informações sobre autenticação no CDK do Airbyte, você pode consultar a [documentação oficial do Airbyte sobre autenticação](https://docs.airbyte.com/connector-development/cdk-python/http-streams#authentication). Se você ainda estiver tendo problemas ou precisar de mais assistência, por favor, forneça mais detalhes sobre a API específica que você está tentando integrar e o tipo de autenticação que ela requer.

@kapa.ai estou usando
Copy code
auth = TokenAuthenticator(auth_header="API-KEY", auth_method="ApiKey", token=config["API-KEY"])
mas estou recebendo erro falando que a chave de api não foi fornecida
k
A message from kapa.ai
Entendo que você está enfrentando um problema com a autenticação usando o
TokenAuthenticator
. O erro que você está recebendo indica que a chave de API não foi fornecida corretamente. Vamos analisar e corrigir o problema. Baseado no código que você forneceu:
Copy code
python auth = TokenAuthenticator(auth_header="API-KEY", auth_method="ApiKey", token=config["API-KEY"])
Há algumas coisas que podemos verificar e ajustar: 1. Verifique se a chave "API-KEY" existe no seu dicionário
config
. O erro sugere que esta chave pode não estar presente ou estar vazia. 2. Certifique-se de que o nome da chave no
config
corresponde exatamente ao que você está usando no
TokenAuthenticator
. Algumas APIs podem usar variações como "api_key", "apikey", ou "API_KEY". 3. O parâmetro
auth_header
deve ser o nome do cabeçalho que a API espera receber, não o nome da chave em si. Aqui está uma versão corrigida que pode resolver o problema:
Copy code
python auth = TokenAuthenticator(token=config["API-KEY"], auth_method="ApiKey", auth_header="X-API-Key")
Neste exemplo: -
token
recebe o valor da chave de API do seu
config
. -
auth_method
permanece como "ApiKey". -
auth_header
é definido como "X-API-Key", que é um nome comum para cabeçalhos de chave de API. Verifique a documentação da sua API para o nome correto do cabeçalho. Além disso, você pode adicionar uma verificação para garantir que a chave de API está presente no config:
Copy code
python if "API-KEY" not in config or not config["API-KEY"]:     raise ValueError("API-KEY não foi fornecida no config")  auth = TokenAuthenticator(token=config["API-KEY"], auth_method="ApiKey", auth_header="X-API-Key")
Se você ainda estiver enfrentando problemas, pode ser útil imprimir o conteúdo do
config
(tendo cuidado para não expor informações sensíveis) para verificar se a chave de API está realmente presente e não está vazia. Para mais informações sobre como configurar a autenticação corretamente, você pode consultar a [documentação do Airbyte sobre autenticação](https://docs.airbyte.com/connector-development/cdk-python/http-streams#authentication). Se o problema persistir, por favor, forneça mais detalhes sobre a API específica que você está tentando integrar e qualquer mensagem de erro adicional que você esteja recebendo.
