Quality Management Export 503 for Digital Channel Interactions in Europe/London

Genesys Cloud WFM

Could use a hand troubleshooting this recurring 503 Service Unavailable error when attempting to export quality evaluation scores for digital channel interactions. The environment is set to Europe/London, and we are processing a legal discovery request that requires a complete chain of custody for all webchat sessions from the last quarter.

The issue appears specifically when filtering by interaction type webchat and including the scorecard_details in the payload. Voice interactions export without issue using the same job configuration.

Steps to reproduce:

  1. Initiate a bulk export job via POST /api/v2/analytics/quality/interactions/export.
  2. Set the date range to the previous 90 days.
  3. Include filter interactionType=webchat.
  4. Add scorecard_details=true to the include list.
  5. Job status transitions to failed within 2 minutes.

The error response body indicates a timeout at the data aggregation layer. We have verified that the S3 bucket permissions are correct and that the recording metadata exists. Is there a known limitation on the volume of digital channel metadata that can be processed in a single export job for the London region? Any guidance on splitting the date ranges or adjusting the payload would be appreciated.
