Is it possible to override the url_base parameter in the manifest.yaml file for a particular stream?

A message from kapa.ai
Based on the provided YAML code, it seems like you are defining a connector for Airbyte using the low-code framework. The code includes definitions for a selector, requester, datetime_cursor, retriever, and default_paginator. These components are used to configure the connector's behavior, such as extracting data from the API, handling authentication, and managing pagination. Here's a brief overview of the components in your YAML code: 1. `selector`: Extracts records from the API response using the 
field_path
parameter. 2. `requester`: Configures the base URL, HTTP method, and authentication for the API requests. 3. `datetime_cursor`: Defines the incremental sync strategy based on datetime values. 4. `retriever`: Combines the record selector and requester to retrieve data from the API. 5. `default_paginator`: Handles pagination using the DefaultPaginator with a page size option and a cursor-based pagination strategy. You can find more information about these components and their properties in the Airbyte documentation: - [Understanding the YAML file](https://docs.airbyte.com/connector-development/config-based/understanding-the-yaml-file) - [YAML Reference](https://docs.airbyte.com/connector-development/config-based/understanding-the-yaml-file/reference) If you have any specific questions or need help with a particular part of the code, feel free to ask!

@kapa.ai for the above defined code i made a new stream which overrirdes the url base but it does not work, can you help
Copy code
flows_stream:
    $ref: "#/definitions/base_stream_with_pagination"
    requester:
      $ref: "#/definitions/requester"
      url_base: "<https://studio.twilio.com/v1>"
    $parameters:
      name: "flows"
      path: "/Flows"
      primary_key: "sid"

@kapa.ai can i keep my 
primary_key: Null
in my manifest.yaml file
k
A message from kapa.ai
Yes, you can set your 
primary_key
to 
null
in your manifest.yaml file. However, this means that the stream will not have a primary key defined for deduplication purposes. If you use the [Incremental Sync - Deduped History](https://docs.airbyte.com/understanding-airbyte/connections/incremental-deduped-history) sync mode, Airbyte will not be able to deduplicate records based on a primary key. If you use the [Incremental Sync - Append](https://docs.airbyte.com/understanding-airbyte/connections/incremental-append) sync mode, a primary key is not required, as this mode does not perform deduplication. Here's an example of how to set the primary key to 
null
in your manifest.yaml file:
Copy code
yaml your_stream:   $ref: "#/definitions/base_stream"   $parameters:     name: "your_stream_name"     primary_key: null     path: "/your_stream_path"
Keep in mind that not having a primary key might cause issues with deduplication if you need it in the future.

@kapa.ai can you explain this error when i read the stream data

@Aazam Thakur That's a great question, but unfortunately it is too long. Can you ask me again but make it shorter? I'm here to help!

@kapa.ai sure this is the shorter version. explain this error i get when i try to read data from a stream

A message from kapa.ai
It seems like you are encountering a syntax error in your code, specifically related to an unexpected token 'slice'. The error message indicates that the parser expected the 'end of print statement' but found 'slice' instead. This error is likely caused by a missing or misplaced closing parenthesis, bracket, or brace in your code. Unfortunately, I cannot provide a specific solution without seeing the relevant code that is causing the error. Please double-check your code for any missing or misplaced closing characters, and ensure that your code follows the correct syntax. If you need further assistance, please provide the relevant code snippet causing the error, and I'll be happy to help.
a
@kapa.ai yes I require further assistance in finding the cause of the problem. Could it be my manifest.yaml file or my catalog.json
