WEM Bulk Export Failing on Legal Hold Metadata

Having some issues getting my configuration to work for the new legal hold export job.

The Create Recording Export Job API returns a 400 Bad Request when filtering for digital channels in the EU region. The payload includes standard chain of custody metadata fields that worked last week. We are using the latest SDK version in Architect. The error message states ‘Invalid filter criteria for legal_hold_type’. This is blocking our discovery request deadline. Need urgent help with the correct JSON structure for the filter object.
