current-context is not set

Error message

current-context is not set

What it means

Guard error in kubectx's CurrentOp.Run: after successfully parsing the kubeconfig, GetCurrentContext() returned an empty string, meaning the kubeconfig file has no current-context set (e.g. a fresh kubeconfig or after `kubectx -u`). The command cannot print a current context because none exists, so it fails instead of printing an empty line.

Solutions

1. Set a current context first with `kubectx <NAME>` or `kubectl config use-context <NAME>`
2. Run `kubectx` to list available contexts and pick one
3. Create or import contexts into the kubeconfig if none exist
