failed to get current context: %w

Error message

failed to get current context: %w

What it means

GetCurrentContext errored while determining which context's namespaces to list. The kyaml read of current-context failed structurally (e.g. non-scalar field); an unset current-context is handled separately below.

Solutions

1. Inspect current-context in each kubeconfig file and fix malformed values
2. Use kubectl config current-context to find the offending file
3. Repair the YAML and rerun kubens
