[Bug] Cannot create a customresourcedefinition that has been exported via 'oc get -o yaml|json' command and then deleted

[radtriste]

Not sure if it is the right place. Please let me know if it is not.

What did you do?

$ oc get crd {CRD_NAME} -o yaml > file
$ oc delete crd {CRD_NAME}
$ oc create -f file

What did you expect to see?
CRD should be imported into the cluster.

What did you see instead? Under which circumstances?
The CustomResourceDefinition "{CRD_NAME}" is invalid: spec.preserveUnknownFields: Invalid value: true: cannot set to true, set x-preserve-unknown-fields to true in spec.versions[*].schema instead

Environment

• OpenShift 4.3-rc3

Possible Solution
Correct the export via oc get command

Additional context
No CR existing in the cluster.
