Bulk Export 500 on WhatsApp Metadata Enrichment

Looking for advice on a recurring 500 error when requesting enriched metadata for WhatsApp interactions in bulk export jobs. The standard export works fine, but adding the legal_hold_status field triggers this failure. We are using the Genesys Cloud API v2 and have verified permissions.

{
 "code": "internalServerError",
 "message": "Unable to process metadata enrichment request."
}

Is this a known issue with digital channel metadata processing?
