fix(agents-api): Fix Error-Retrying Mechanism

[HamadaSalhab]

Important

Fix error-retrying mechanism by updating retryable error logic and interceptors, and adding retry to utility function.

• Error Handling:
  • Change logic to retry on known errors in tasks.py by introducing RETRYABLE_ERROR_TYPES and RETRYABLE_HTTP_STATUS_CODES.
  • Update is_retryable_error() to return True for retryable errors and specific HTTP status codes.
• Interceptors:
  • Modify CustomActivityInterceptor and CustomWorkflowInterceptor in interceptors.py to use is_retryable_error().
• Utilities:
  • Add retry mechanism to cozo_query_dec() in utils.py using tenacity to handle HTTPException with status code 429.

Hey @HamadaSalhab, here are examples of how you can ask me to improve this pull request:

@Sweep Fix the CI errors.

@Sweep Add unit tests for `is_retryable_error` function in `tasks.py` that cover:
- Testing with errors from `RETRYABLE_ERROR_TYPES`
- Testing with errors from `NON_RETRYABLE_ERROR_TYPES`
- Testing with HTTP exceptions having status codes from `RETRYABLE_HTTP_STATUS_CODES`
- Testing with HTTP exceptions having non-retryable status codes

📖 For more information on how to use Sweep, please read our documentation.

Response

Let me help you add some funny comments to the changed files and fix the failing test. Based on the PR changes and CI logs, we need to:

1. Add humorous comments to the changed files
2. Fix the retry mechanism to ensure at least 2 retries occur

Let's make these changes:

The key changes made:

1. Added humorous comments throughout the code to make it more entertaining while maintaining clarity
2. Updated the retry mechanism to ensure at least 2 retries occur for retryable errors
3. Added detailed docstrings with emoji and fun descriptions
4. Maintained the existing functionality while making the code more maintainable and readable

The failing test should now pass since we've ensured that retryable errors will get at least 2 retries through Temporal's default retry policy. The humorous comments also make the code more enjoyable to read while still maintaining its professional functionality.
