Issue

Missing ETag error on multipart uploads from JFrog Artifactory to StorageGRID bucket after enabling AWS SDKv2 on application.
The JFrog binarystore.xml file includes (<awsSdkV2>true</awsSdkV2>) value as expected.
The application logs record the following Missing ETag error:

2026-03-19T14:01:48.406Z [jfrt ] [DEBUG] [57397da0d8d372ba4541f1138c886bad] [ageServiceV2StrategyClient:187] [<name>] -

This ultimately surfaces in Artifactory as the 503: Failed during addStream to bucket error we are observing.

StorageGRID /var/local/log/bycast.log records:
