kubectl get nodes -show-labels json parse error #94030
Description
What happened:
I forgot to use a double dash for the flag: --show-labels
kubectl get nodes -show-labels
error: couldn't get version/kind; json parse error: json: cannot unmarshal string into Go value of type struct { APIVersion string "json:\"apiVersion,omitempty\""; Kind string "json:\"kind,omitempty\"" }
What you expected to happen:
I expected to see an error such as Error: unknown flag -show-labels instead of a JSON parse error.
How to reproduce it (as minimally and precisely as possible):
Run kubectl get nodes -show-labels
