Quality Management API bulk export fails for digital channels

I’m completely stumped as to why the Quality Management API returns a 500 Internal Server Error when requesting bulk exports for digital channel interactions. The endpoint /api/v2/quality/evaluations/exports works for voice but fails consistently for chat and email.

The error payload indicates a null pointer exception in the metadata processing module. This happens specifically when the legal_hold filter is active.

Environment is Genesys Cloud EU (eu-west-1). We are using the latest SDK version 2.145.0.

Need to know if this is a known issue with WFM integration for digital channels or if the request body format needs adjustment.
