current-context is not set

Error message

current-context is not set

What it means

Guard error in formatNamespaceList (kubens/list.go): GetCurrentContext() returned an empty string — the kubeconfig has no current-context set. The list/highlight logic needs the current context to determine the active namespace, so listing aborts.

Solutions

1. Set a context with `kubectx <NAME>` before listing namespaces
2. Create contexts in the kubeconfig if none exist
