You've selected the Backups tab in UI. If you have neither configured a backup location nor set the required environment variable for UI deployment these errors are expected.

[droslean]

well, the clusters are completely missing. It's not the specific backups tab. The UI can't find any of the clusters that haven't been created by the UI.

[droslean]

To replicate this, just create a cluster manually and you will see that the UI won't be able to find it. If you create a cluster through the UI, the cluster will be listed as normal. This is 100% a BUG in the UI.

Sorry, I cannot replicate this. I tested in minikube adding the operator and ui using the provided kustomizations. No matter if I create a cluster with kubectl create or via UI, both clusters are listed. What setup have you tested?

I am experiencing the exact same thing here. Clusters are all defined in namespaces different from the default namespace.

UPDATE: And that was already the issue: targetNamespace needs to be *...
