WEM adherence export 400 on REGION update

Problem
The WEM dashboard won’t pull adherence data after updating the REGION mapping. Mic stays hot during the export window.

{ "schedule_export_id": "abc-123", "region": "us-east-2" }

Error
POST /api/v2/wfm/data/exports throws a 400 with “Invalid SCHEDULE_EXPORT configuration”.
Question
Need to know if the QUEUE_ID is mandatory here.
