After a recent upgrade to argo-cd v2.4.3 coming from v2.2.x we're seeing the following error in argocd-application-controller component:

The error is constantly outputed, as you can see it is being reported for both clusters we have under argo-cd management.

I guess it is very related to this last commit from release v0.7.0 @leoluz

Let me know if you need more information and I'll gladly help in troubleshooting this issue as I'm a bit lost.

The log level is wrong. This is basically a warning message and ArgoCD should work normally.

Thanks @leoluz , I confirm that apparently ArgoCD is working fine.

I've opened a PR to change the log level.
