@Marvin I recently added more environment variables to the base job configuration in my work pool in Prefect. Could that have caused this error? If so, how can I fix it?

File "/usr/local/lib/python3.11/site-packages/prefect_aws/workers/ecs_worker.py", line 1679, in _create_task_run
    task = ecs_client.run_task(**task_run_request)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/local/lib/python3.11/site-packages/botocore/client.py", line 569, in _api_call
    return self._make_api_call(operation_name, kwargs)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/local/lib/python3.11/site-packages/botocore/client.py", line 1023, in _make_api_call
    raise error_class(parsed_response, operation_name)
botocore.errorfactory.InvalidParameterException: An error occurred (InvalidParameterException) when calling the RunTask operation: Container Overrides length must be at most 8192

The error you're encountering,

InvalidParameterException: Container Overrides length must be at most 8192

, is due to exceeding AWS's limit for the length of the

ContainerOverrides

parameter in ECS task definitions. This can happen if you've added too many environment variables or if their combined size exceeds this limit. Here's how you could address the issue: 1. Reduce Environment Variables: Review the environment variables you've added to the base job configuration in your Prefect deployment. You might want to cut down on the number of variables or their lengths to ensure you stay within the limit. 2. Consolidate or Compress Data: If possible, consolidate related variables into a single string or use shorter variable names. You can also consider compressing configuration data if that makes sense for your use case. 3. Use Secrets Management: For large or sensitive configuration data, use a secrets management service like AWS Secrets Manager or Prefect's own secret storage. This keeps your environment variables shorter and helps with security. For detailed documentation on setting job variables and handling environment variables in Prefect, you can refer to the following: - Prefect 2.x: Overriding Job Variables - Prefect 3.x: Infrastructure Concepts I looked into related GitHub issues, but none were found specifically addressing this ECS parameter limit. If the problem persists, you might consider seeking more direct community help or raising an issue if it's not already addressed. Remember, a tidy environment variable list makes for a happy ECS task. Well, as happy as a computer program can be. ☺️
