Why does this setting cause WFM API 409 Conflict during bulk schedule publish for Chicago team?

Background
Our workforce management process relies heavily on the Genesys Cloud WFM API to publish weekly schedules for our Chicago-based agents. We are currently running Genesys Cloud version 2024-03-01. The workflow involves calculating optimal shifts based on agent preferences and then pushing the final schedule via the /api/v2/wfm/schedules endpoint.

Recently, the bulk publish operation started failing intermittently with a 409 Conflict error. The error payload indicates a resource conflict, but no specific agent ID is highlighted in the initial response. This is happening right after agents approve shift swaps in the self-service portal. The WFM API seems to be locking the schedule resource, preventing the bulk update from completing.

  • Verified that all shift swaps have been fully committed and the agent availability windows are updated in the UI before triggering the API call.
  • Checked the Activity Log for any concurrent WFM operations that might be holding a lock on the schedule resource, but found no overlapping processes.

Is there a specific setting or race condition related to shift swaps that causes this lock? We need a reliable way to publish schedules without manual intervention.
