POST /api/v2/recordings/bulkexport returns HTTP 502 Bad Gateway immediately. The target is a BYOC edge in eu-west-1, and the payload contains only basic filter criteria for voice recordings. Direct API calls to the same endpoint via public cloud work fine. Does the BYOC edge require a specific IAM policy for S3 write access during export job creation?
If I remember correctly…
Does the BYOC edge require a specific IAM policy for S3 write access during export job creation?
The 502 is likely not an IAM permission issue. In load testing scenarios, a 502 Bad Gateway often points to a backend service timeout or a connection drop between the edge proxy and the internal recording service, rather than a permission denial (which usually returns 403).
Check if the BYOC edge has sufficient capacity for concurrent bulk export requests. If multiple users trigger exports simultaneously, the internal service might be overwhelmed.
Try adding a simple delay in your JMeter script to space out the requests:
<ConstantTimer guiclass="TestBeanGUI" testclass="ConstantTimer" testname="Constant Timer" enabled="true">
<stringProp name="ConstantTimer.delay">2000</stringProp>
</ConstantTimer>
Also, verify the X-Genesys-Request-Id header is unique for each request. Duplicate IDs can cause unexpected failures in bulk operations. Monitor the edge logs for upstream timed out errors.
It varies, but usually the 502 error in BYOC environments during bulk export initiation is rarely about IAM permissions for S3 writes at the moment of job creation. The job creation endpoint is lightweight metadata. The timeout usually occurs because the internal recording service on the BYOC edge cannot establish a timely connection to the S3 bucket to validate the storage path or check for existing export jobs. In my load tests with JMeter, I see this pattern when the VPC endpoints for S3 have strict throughput limits or when the security groups block outbound traffic from the recording service pod to the S3 VPC endpoint. Check the CloudWatch logs for the genesys-recording-service on your BYOC edge. Look for ConnectionTimeout or SocketTimeout errors. Also, verify that the IAM role attached to the recording service has s3:ListBucket and s3:GetObject permissions, not just PutObject. The service needs to list the bucket to ensure the export directory is accessible before creating the job. If the network latency between the edge and S3 is high, increasing the timeout in the recording service configuration might help, but fixing the network path is the better solution. Ensure the S3 bucket is in the same region as the BYOC edge to reduce latency. If the issue persists, try creating a smaller test export with a single recording to isolate if it is a capacity issue or a configuration error.
