Can you please describe what the problem is? Maybe attaching a screenshot? Is there a link to other bug ticket which can be closed? Does it need to be back-ported to Airflow 2.10-line?

Backport failed to create: v2-10-test. View the failure log Run details

Status	Branch	Result
❌	v2-10-test

You can attempt to backport this manually by running:

cherry_picker e8f55b3 v2-10-test

This should apply the commit to the v2-10-test branch and leave the commit in conflict state marking
the files that need manual conflict resolution.

After you have resolved the conflicts, you can continue the backport process by running:

cherry_picker --continue
