no context exists with the name: %q

Error message

no context exists with the name: %q

What it means

Validation guard: the lookup succeeded but the requested context name (s.target) does not exist in any kubeconfig file, so the isolated shell cannot be started for it. Pure user-input error naming the offending context via %q.
