How would I debug a problem with a custom connector in airbyte?

Debugging a custom connector in Airbyte involves several steps: 1. Enable Detailed Debug Messages: During the development of your connector, you can enable the printing of detailed debug information during a sync by specifying the

--debug

flag. This will allow you to get a better picture of what is happening during each step of your sync. You can also emit custom debug information from your connector by introducing your own debug statements. Here is an example:

python python main.py read --config secrets/config.json --catalog sample_files/configured_catalog.json --debug    self.logger.debug(    "your debug message here",    extra={    "debug_field": self.value,    "custom_field": your_object.field    }   )

airbyte-platform

repository, you can enable

LOG_CONNECTOR_MESSAGES=true

to log the messages the Airbyte platform receives from the source and destination when debugging locally. For example:

bash LOG_CONNECTOR_MESSAGES=true VERSION=dev docker compose up

airbyte

repository. After building the connector image and updating the version number to use your docker image tag (default is

dev

), you can run a sync with that connector, which will use your local docker image. This can help you identify any issues with your custom connector.

bash ./run-ab-platform   docker build ./airbyte-integrations/connectors/<connector-name> -t airbyte/<connector-name>:dev
