error applying update: %w

Error message

error applying update: %w

What it means

In updateAddon, the applier (typically kubectl-apply logic) failed to apply the manifest bytes that were successfully fetched. This wraps the apply error; the underlying cause is in the wrapped error (API rejection, malformed manifest objects, or cluster connectivity).

Solutions

  1. Inspect the wrapped error for the Kubernetes API rejection reason
  2. Check the addon manifest for invalid or unsupported resources
  3. Verify the cluster API server is reachable and RBAC allows the apply
Defensive patterns

Strategy: try-catch
