I’ve spent hours trying to figure out why the POST /api/v2/wfm/schedule/publication endpoint returns a 422 Unprocessable Entity when including agent preference overrides.
The request body is valid JSON and matches the schema in the documentation exactly. We are running Genesys Cloud version 2023-11 in the US-East region.
The error message says “Invalid schedule configuration,” but no specific field is flagged. This happens only when shift swaps are active for the upcoming week.
Has anyone seen this behavior with the WFM API during high-volume schedule publications?
You need to check the timezone mapping in your payload.
During our Zendesk-to-GC migration, we hit this exact 422 error when agent preferences didn’t align with the business unit’s timezone settings. In Zendesk, we handled availability differently, often relying on agent-side settings without strict server-side validation for overrides. Genesys Cloud is stricter. If the shift swap times in your JSON use a different timezone offset than the publication context, the engine rejects the whole batch.
Make sure the start_time and end_time fields in the preference overrides are explicitly in UTC. The documentation hints at this, but it’s easy to miss. Also, verify that the agents involved in the swaps are actually assigned to the business unit being published. If an agent is in a different BU, the preference override fails silently with a generic “Invalid schedule configuration” error. We had to script a pre-validation check to catch these BU mismatches before publishing. It saved us hours of debugging. Try isolating the swaps to one agent and see if it passes. That usually highlights the rogue record.
