error listing namespaces: %v

Error message

error listing namespaces: %v

What it means

RunGetAddons lists all namespaces via the Kubernetes API to map addons to namespaces; this wraps that LIST call failing. The client was built successfully, so this is an API-level failure: server unreachable, RBAC denial, or a transient error.

Solutions

1. Check API server reachability and cluster health
2. Verify the user/service account has permission to list namespaces
3. Retry; transient API errors are common during control-plane churn
