Can anyone explain why the bulk export job fails with a 500 Internal Server Error when requesting chain of custody metadata for WhatsApp interactions in a BYOC environment? The standard export works fine, but adding the legal_hold_status field triggers this error consistently. We are using Genesys Cloud v2.14 with the Bulk Export API v2. The S3 destination is configured in EU-West-1. The job completes successfully for voice recordings but fails immediately when digital channel metadata enrichment is enabled. The error response does not provide specific details, only a generic server failure message. We have verified permissions on the S3 bucket and confirmed the IAM role has full access. This is blocking a critical legal discovery request. Any insights on known issues with digital channel metadata in BYOC setups?
