Data Action failure during WFM schedule publish integration

Anyone know why the Genesys Data Action returns a 400 Bad Request when triggered by the WFM schedule publication webhook?

The integration is failing specifically for the America/Chicago timezone batch.

  • Endpoint: POST /api/v2/integrations/dataactions
  • Payload: Contains standard shift swap validation data
  • Error: “Invalid field mapping for agent availability”

The schedule publishes fine in the UI, but the downstream data sync breaks immediately after.
