Stuck on a problem and need help troubleshooting a recurring integration failure in our WFM workflow. We are running a Python script using the Genesys Cloud SDK (v2.140.0) to synchronize external shift data into our Chicago-based org. The script successfully creates individual schedules via the /api/v2/wfm/schedules endpoint, but fails when attempting the bulk publish operation through /api/v2/wfm/schedules/publish. The API returns a 409 Conflict error with the message ScheduleConflict: Overlapping shifts detected for agent ID 12345. This is puzzling because the script validates for overlaps locally before sending requests. The agents involved are part of a high-volume shift swap pool, and their availability windows are updated dynamically. The error persists even after clearing the cache and retrying with a fresh token. We have verified that the timezone settings (America/Chicago) are consistent across the agent profile, the schedule object, and the publishing context. The issue seems isolated to agents who have pending shift trade requests that haven’t been finalized. Is there a known limitation with publishing schedules while shift trades are in a PENDING state, or does the bulk publish endpoint require a different conflict resolution strategy compared to individual publishes?
The way I solve this is by checking the schedule version numbers before the publish call. The 409 conflict often happens when the local copy of the schedule diverges from the server state during the bulk creation phase. In my experience with bulk exports and legal holds, data integrity is key, so ensuring the version field matches is critical.
First, fetch the current schedule details immediately after creation to get the latest version integer. Then, include that specific version in your publish payload. This prevents the API from rejecting stale data.
Here is a quick snippet showing how to handle the version update in Python:
# After creating schedule
schedule_id = response.id
# Fetch latest version
latest_schedule = wfm_client.get_schedule(schedule_id)
publish_payload = {
"schedules": [
{
"id": schedule_id,
"version": latest_schedule.version
}
]
}
See the API docs for version control here: WFM Schedule API. This approach resolves most concurrency issues in bulk operations.
