current-context is not set

Error message

current-context is not set

What it means

Guard error in kubens's CurrentOp.Run: GetCurrentContext() returned an empty string after a successful parse, so the kubeconfig has no current-context set. kubens cannot look up the active namespace of a context that does not exist, so it aborts.
