Can you confirm the applicable kubernetes version? My kubernetes 1.20 report is wrong.

kubernetesL1.20 permission-manager:1.9.0
error: error validating "permission-manager/crd.yml": error validating data: [ValidationError(CustomResourceDefinition.spec.versions[0].schema): unknown field "properties" in io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1.CustomResourceValidation, ValidationError(CustomResourceDefinition.spec.versions[0].schema): unknown field "type" in io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1.CustomResourceValidation]; if you choose to ignore these errors, turn validation off with --validate=false

I also encountered this problem.

Error from server (BadRequest): error when creating "crd.yml": CustomResourceDefinition in version "v1" cannot be handled as a CustomResourceDefinition: strict decoding error: unknown field "spec.versions[0].schema.properties", unknown field "spec.versions[0].schema.type"

Seems like crd has a bug in formatting, since they did linting in 1.8.0 and I can apply it after these changes:

      schema:
        openAPIV3Schema:
          type: object
          properties:
            spec:
              type: object
              properties:
                name:
                  type: string
                  minLength: 2
