%!v(PANIC=String method: reflect.Value.Bytes of non-byte slice)

Checklist:

• I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• I've included steps to reproduce the bug.
• I've pasted the output of argocd version.

Describe the bug

• Logs show a PANIC
• Logs show a suspicious %!v
• Logs may include something that looks suspiciously like credentials (yes, I'm running at info level, so this might be on me, but ArgoCD does try to avoid leaking credentials into logs, so...)

To Reproduce

Sorry, I don't really know what triggered it. I did switch the branch for my applications (including cascades at times)...

Expected behavior

None of the items in the bug section

Hey there! Found the same issue when trying to update application parameters.

Running command under local admin account:

argocd app set app --kustomize-image=registry.gl.com/app:test

Logs:

I believe it relates to ApplicationSet. When i had app-root -> appset -> app, trying to set image parameter in latest app led me to the logs mentioned above. Also I tried to get logs from applicationset controller with no luck - no errors were there.

When i changed to schema to app-root -> app everything started to work as expected.

Maybe it could help. Thanks.

Any updates on this issue ? Facing the same error when updating and creating an app with parameters in v2.9.1
