Additional context

I confirm that it is fixed. note for self, need to inject kubeconfig using chectl server:inject or for now when being in multiuser (until this issue fixed): 1/ Copy your local kubeconfig to the clipboard. Use kubectl config view --raw --flatten --minify to get it. 2/ Paste the copied kubeconfig into the ~/.kube/config file into plugin sidecar (Right menu My Workspace -> Plugins -> vscode-kubernetes-xxx -> New Terminal) (can use vi to create the file content) 3/ Refresh Clusters tree with Refresh button

@apupier just make sure that your workspace is started with the next versions of Che Theia and K8s plugin images. If you deleted your minikube, obviously the newest images have to be downloaded.

I’ve also checked it on my minikube. Probably it’s really fixed by https://github.com/eclipse/che-theia/pull/468
