Stuck on a consistent 500 Internal Server Error when triggering a custom Data Action to export Web Chat recording metadata to our S3 bucket for a legal discovery case. The standard bulk export job via the Recording API v2 works fine for voice recordings, but fails specifically for digital channels in the eu-west-2 region.
The error occurs during the ‘Write to S3’ step in the Architect flow. The flow successfully retrieves the recording details using the ‘Get Recording Details’ action, but crashes when attempting to map the JSON payload to the S3 upload action. The error message returned is generic: Failed to execute data action. Reason: Internal server error. No specific validation error codes are provided in the Architect logs.
Environment details:
Region: eu-west-2 (London)
Genesys Cloud Version: Current (as of Oct 2023)
Data Action Version: v1.2
SDK: Python 3.9 for custom preprocessing logic
S3 Bucket: Located in eu-west-2, same region as Genesys instance
Recording Type: Web Chat (Digital Channel)
The issue appears to be related to the payload size or structure of the digital channel transcript metadata. Voice recordings export without issue. I have verified that the IAM role attached to the S3 bucket has full s3:PutObject permissions and that the bucket policy allows access from the Genesys Cloud service principal. The chain of custody requires this specific metadata to be preserved, so we cannot skip the detailed transcript export.
Has anyone encountered similar issues with Data Actions failing on digital channel exports in the London region? Is there a known limitation on the payload size for the ‘Write to S3’ action when handling large transcript objects? Any guidance on debugging the specific cause of the 500 error would be appreciated, as the Architect logs lack detail.
If I remember correctly, region mismatches are the usual culprit, especially when moving from Zendesk’s simpler global buckets to AWS-specific endpoints. Since the voice exports work, the IAM role is likely fine, but the Digital Channel metadata might be hitting a different S3 endpoint or missing a specific header required for chat recordings in eu-west-2.
Double-check the Data Action’s AWS Region setting; it must explicitly match eu-west-2, not defaulting to us-east-1.
Verify the bucket policy allows s3:PutObject from the specific Genesys Cloud IP ranges for that region.
Add a Content-Type header of application/json in the Write to S3 step, as chat metadata is often JSON-formatted unlike voice blobs.
Enable verbose logging on the Data Action to see if the error is a 403 Forbidden (permissions) or 500 (endpoint mismatch).
This setup feels very similar to the timestamp drift issues we saw during our migration. Adjusting the region explicitly usually clears up the 500s.
Check your Data Action configuration for explicit region overrides. The suggestion regarding IAM permissions is valid, but in my experience with multi-site deployments, the issue often lies in the endpoint resolution rather than permissions. When exporting digital channel metadata, the platform sometimes defaults to the global endpoint if the region is not strictly enforced in the integration settings.
The 500 error typically manifests as follows:
“Internal Server Error: Failed to resolve S3 endpoint for eu-west-2. Defaulting to global endpoint resulted in access denial.”
Ensure the AWS Region field in the Data Action is hardcoded to eu-west-2. Do not leave it blank or set to “Auto-detect,” as the platform may route the request through a different availability zone that does not support the specific metadata schema for Web Chat recordings. Additionally, verify that the S3 bucket policy allows cross-region requests if your primary tenant is hosted elsewhere. This usually resolves the discrepancy between voice and digital channel exports.
