Just noticed that the adherence event ingestion pipeline is failing for about 20% of our Chicago-based agents during peak morning wrap-up times. The specific endpoint POST /api/v2/wfm/schedules/adherence-events is returning a 400 Bad Request with the message Invalid state transition: Agent cannot move from READY to AVAILABLE without a prior PAUSED state. This is happening exclusively when agents perform rapid status toggles in the Genesys Cloud desktop app while simultaneously using the self-service schedule adjustment tool. We are running the Genesys Cloud Platform version 2024-10-15 and utilizing the Python SDK v2.14.0 for our custom adherence monitoring script. The logs show that the desktop client sends the READY to PAUSED transition, but the PAUSED to AVAILABLE transition seems to arrive at the API before the initial state change is fully committed in the WFM database, causing the validation logic to reject the second event as an illegal jump. I have verified that the agentId and scheduleId parameters are correct and that the timestamps are within the acceptable drift window of 500ms. The issue does not occur when agents follow the standard single-step status change workflow, suggesting a race condition in how the API processes concurrent state updates from different client interfaces. Is there a recommended retry strategy or a specific header we need to include to ensure sequential processing of these adherence events? We have tried adding a 1-second delay in the SDK call, which reduces the error rate but does not eliminate it, and it negatively impacts real-time adherence reporting. Any insights into the internal locking mechanism for adherence state changes would be appreciated, as this is causing significant discrepancies in our weekly schedule adherence reports.
This looks like a race condition in the event ingestion pipeline rather than a pure API configuration error. The Genesys Cloud WFM engine expects a strictly linear state machine for adherence tracking. When agents toggle status rapidly, the client SDK may batch events and send them out of chronological order relative to the server’s processing queue.
Invalid state transition: Agent cannot move from READY to AVAILABLE without a prior PAUSED state
The fix usually involves adding a small jitter or debounce logic in the integration layer before posting to /api/v2/wfm/schedules/adherence-events. If you are using a custom connector, ensure each event includes a precise timestamp and that your client sorts the batch by time before sending. For JMeter load testing, avoid generating more than 5 status changes per second per virtual user. This prevents the 400 error by allowing the WFM engine to process the intermediate PAUSED state correctly. Check the event-id uniqueness as well to avoid duplicate processing failures.
This is actually a known issue with the event ingestion pipeline. The order of events in the batch matters more than the timestamps. Ensure the client SDK sends events strictly chronologically to avoid these 400 errors.
