After upgrading Red Hat Quay to v3.16.1, the registry logs show repeated error-level log entries originating from the storage cloud layer with OTEL instrumentation enabled.

The errors appear during S3 (Ceph RGW) operations and include full AWS-style request headers logged at ERROR level under:

gunicorn-registry stdout | 2026-01-21 21:13:14,868 [311] [ERROR] [storage.cloud] [OTEL] request xxx}
gunicorn-registry stdout | 2026-01-21 21:13:14,930 [309] [ERROR] [storage.cloud] [OTEL] request xxx} 

Despite these errors:

• Image push operations work as expected

• Image pull operations work as expected

• No functional impact has been observed so far

This behavior was not present before upgrading to v3.16.1, suggesting a regression or logging-level issue introduced in this release, possibly related to OpenTelemetry instrumentation for storage operations.

Additional Note - this is observed with a customer with standalone quay deployment
