S3 Data Action fails on Legal Hold metadata injection

Stuck on a 400 Bad Request when triggering a Data Action to push recording metadata to S3. The payload includes legal_hold_id tags for EU-1 discovery requests, but the integration rejects the object size limit. Is there a known constraint on metadata length for bulk exports?

This is typically caused by the default export payload schema in Genesys Cloud not including custom metadata fields like legal_hold_id or audit_timestamp unless explicitly configured via a custom view or data action definition. Coming from Zendesk, where ticket fields are just attributes, GC requires strict schema alignment for S3 integrations. The 400 error often masks a schema validation failure rather than a raw size issue.

To fix this:

  • Verify the Data Action input schema includes the legal_hold_id field as a string type.
  • Ensure the S3 bucket policy allows PUT requests with the specific metadata headers.
  • Check if the total payload exceeds the 256KB limit for metadata headers in S3, not just the object size.
  • Use a JSON transformer to strip null values before sending to S3, as empty fields can cause validation errors in strict modes.

In Zendesk, we just pushed everything. Here, precision matters. Try reducing the metadata payload first to isolate the issue.
