Quality Export API 422 on Digital Channel Evaluation Filter

Hey everyone, I’ve run into a really strange issue with the Quality Management export endpoint. The system refuses to process digital channel evaluations in the bulk export job.

Environment: Genesys Cloud EU-West-1, Python SDK 2.14.0.
The request returns a 422 Unprocessable Entity when including chat or whatsapp in the filter.

POST /api/v2/quality/evaluations/export
Status: 422
Body: {"code":"bad.request","message":"Invalid filter criteria for digital channels"}

Voice recordings export without issue. The legal discovery team needs these transcripts for the chain of custody audit. The documentation states that digital channels are supported for export.

“The export job supports all evaluation types, including voice, chat, and co-browsing. Ensure the user has the Quality:Export permission.” - Genesys Cloud API Docs

The user has the correct permissions. The job creates successfully with voice filters. It fails immediately with digital filters. Is there a known limitation in EU-West-1? The audit trail requires this data for the current quarter. The S3 integration is active and working for other export types. Need to resolve this before the legal hold deadline.
