no contexts found in the kubeconfig file

Error message

no contexts found in the kubeconfig file

What it means

Guard error in fzfPickContext (shell_session.go): ContextNames() returned zero entries, so there is no context to offer for the scoped shell session. The kubeconfig loaded but contains no contexts, so the interactive picker cannot proceed.
