STRATCONN-6767 - [GEC] Treat updated events as add in mirror sync mode

[varadarajan-tw]

Fixes the Customer Match User List action in the Google Enhanced Conversions destination failing with "Could not determine operation type" when RETL sends updated events in mirror sync mode.

When syncMode is mirror, RETL subscribes to new, updated, and deleted events. However, the destination only handled new (→ ADD) and deleted (→ REMOVE), silently dropping or erroring on updated events. Since Google's API doesn't support an Update operation, updated events should be treated as add — the user identifiers may have changed and need to be re-synced.

Changes

• functions.ts: Two places where mirror mode determines operation type now include updated → add mapping:
  • determineOperationType (batch path)
  • The non-batch identifier loop
• __tests__/userList.test.ts: Two new tests covering the updated event in mirror mode (single-event and batch paths)

Testing

Had to test directly on staging with Integrations as we don't have RETL subscription. This chane is pretty much contained to RETL -> GEC flow. So, this testing is sufficient.
Test Results

• Added unit tests for new functionality
• Tested end-to-end using the local server
• [If destination is already live] Tested for backward compatibility of destination. Note: New required fields are a breaking change.
• [Segmenters] Tested in the staging environment
• [Segmenters] [If applicable for this change] Tested for regression with Hadron.

Security Review

• Reviewed all field definitions for sensitive data (API keys, tokens, passwords, client secrets) and confirmed they use type: 'password'

New Destination Checklist

• Extracted all action API versions to verioning-info.ts file. example

Changes:

• Map event_name = updated → add when syncMode = mirror in both non-batch and batch operation-determination paths.
• Add unit tests covering updated events in mirror mode for single-event and batch execution.
