resolving namespace: %w

Error message

resolving namespace: %w

What it means

For namespaced resources without an explicit namespace, updateRuntimeObject calls resolveNamespace, which reads the kubeconfig via kubectx.CurrentConfig to find the context's default namespace. This error wraps a failure to load the current kubeconfig configuration.

Solutions

1. Set an explicit namespace in the manifest metadata so resolveNamespace is never invoked
2. Ensure kubeconfig is readable: `kubectl config view --minify` should succeed
3. Fix or regenerate the kubeconfig file(s) referenced by KUBECONFIG

Example fix

// before
metadata:
  name: my-app
// after
metadata:
  name: my-app
  namespace: default

if ns == "" {
    ns = os.Getenv("POD_NAMESPACE")
    if ns == "" {
        ns = "default"
    }
}

ns, err := resolveNamespace(namespace, kubeContext)
if err != nil {
    return fmt.Errorf("no namespace on object and kubeconfig unreadable: %w", err)
}

When it happens

Trigger: A namespaced resource with empty namespace on both the object and the artifact, plus kubectx.CurrentConfig() failing — unreadable/missing kubeconfig or invalid MERGE/KUBECONFIG setup.

Common situations: Missing kubeconfig in CI while manifests omit `namespace:`; corrupted kubeconfig; KUBECONFIG merging multiple files where one is invalid.
