Describe the bug

After upgrading from 2.12.0 to 2.13.0 we found that resources show progress status when it's already healthy.
This means UI can't get actual status from Argo CD server.

Regular refresh of window in browser helps.

I see error in developer console of browser

For some reason it's doing calls to:

appNamespace=undefined

To Reproduce

Upgrade to 2.13.0 version

Expected behavior

No error

Screenshots

Version

Paste the output from `argocd version` here.

Logs

Found that version 2.12.0 doing calls to appNamespace=. But response is 200 there.

It seems it is connected with http path. If I open /applications/argocd/{name} with specifying application namespace, instead of /applications/{name} without namespace, it works.
