WFM Integration Error 500 in EU-West BYOC

Genesys Cloud WFM

What is the reason the workforce management integration endpoint returns a 500 Internal Server Error when pushing shift data for our EU-West BYOC instance? The payload validates correctly against the schema, yet the failure persists across multiple attempts.

  1. Construct the JSON body with standard shift attributes.
  2. POST to the /api/v2/wfm/scheduling/shifts endpoint.
  3. Observe the immediate 500 response with no detailed error message in the logs.
