Encountering a 409 Conflict when agents attempt to finalize shift swaps via the self-service portal. The WFM API logs indicate a timezone boundary collision between America/Chicago and the scheduled wrap-up time. This happens exclusively for swaps crossing Saturday night. Has anyone encountered similar validation logic errors in the latest release? Checking Shift Swap Rules but the documentation is vague on edge cases.
As far as I remember, the 409 conflict often stems from how the WFM engine handles timezone offsets during weekend transitions, especially with Daylight Saving Time boundaries. The system might be double-counting the offset change or validating against a cached schedule state.
When testing this in JMeter, ensure the Accept-Language header is set correctly, as locale settings can influence date parsing. Also, check if the wrap-up time pushes the swap into a new scheduling period that is already locked.
Consider adding a small delay in the API sequence to allow the WFM cache to refresh. Here is a quick JMeter config snippet for the swap request:
| Parameter | Value |
|---|---|
| Endpoint | /api/v2/wfm/schedules/shiftswaps |
| Method | POST |
| Header | X-Genesys-Request-Id: unique-id |
Try disabling the “auto-approve” flag temporarily to see if the validation error persists. It might be a backend race condition rather than a logic error in the swap rules themselves.
