no context exists with the name: "%s"

Error message

no context exists with the name: "%s"

What it means

Generic validation error raised in switchContext when the kubeconfig reports (via kc.ContextExists) that the context name supplied by the caller does not exist in the loaded kubeconfig. The input at fault is the target context <NAME> argument: it is neither present in the config nor a valid entry, so the switch is refused before any modification is made.
