WFM Schedule Publish API returns 500 Internal Server Error during Chicago Weekly Cycle

Could someone clarify why the WFM schedule publish endpoint is suddenly failing with a 500 Internal Server Error when executing our standard weekly publish sequence? This issue emerged last Tuesday during the America/Chicago cycle.

  • Environment: Genesys Cloud BYOC Edge
  • Endpoint: /v2/wfm/schedules/publish
  • Payload Size: 450 agents
  • Error Code: 500 Internal Server Error

The response body contains no useful details, just a generic server error. Previous publishes completed successfully without modification to the API call structure.
