Improve error handling for missing object tag in connect_timelapse

[arjunrajlab]

Summary

Improved error handling in the connect_timelapse worker to gracefully handle missing or invalid object tags instead of raising exceptions. The worker now sends a user-friendly error message and returns early without proceeding with annotation processing.

Key Changes

• Early validation: Added explicit check for object_tag before attempting to use it, with clear error messaging
• Better error messages: Enhanced sendError call to include an info parameter with actionable guidance for users
• Graceful failure: Changed from raising ValueError to calling sendError and returning, allowing the worker to fail gracefully
• Comprehensive test coverage: Added three new test cases covering different scenarios:
  • Empty list for object tag
  • None value for object tag
  • Missing Object to connect tag key entirely

Implementation Details

• The validation now occurs immediately after extracting the object_tag from workerInterface
• All three failure modes (empty list, None, missing key) are handled by the same validation logic
• Tests verify that sendError is called with appropriate messaging and that downstream operations (like getAnnotationsByDatasetId) are not executed
• The error message guides users to specify the required parameter in the worker interface configuration
