Unable to unset standard storage class in GKE using kubectl

[lservini]

Trying to unset the standard storage class as default using

kubectl patch storageclass standard -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'

get

storageclass.storage.k8s.io "standard" not patched

Doing it manually with

kubectl edit storageclass standard

works fine

kubectl version
