I am trying to use ApiextensionsV1beta1Api to create a custom resource definition though kubernetes python client

with kubernetes.client.ApiClient(configuration) as api_client:
    self.client_custom_resource_def = kubernetes.client.ApiextensionsV1beta1Api(api_client)

spec = {"group": "kgosalia.com", "scope": "Namespaced",
                "metadata": {"name": "kgosaliaconfigs.kgosalia.com"},
                "versions": [{"name": "v1", "served": True, "storage": True}],
                "names": {"kind": "CustomResourceDefinition", "plural": "kgosaliaconfigs"}}

def create_custom_resource_definition(self, spec):
    body = kubernetes.client.V1beta1CustomResourceDefinition(spec=spec)
    try:
        api_response = self.client_custom_resource_def.create_custom_resource_definition(body)
        pprint(api_response)
    except ApiException as e:
        print("Exception when calling ApiextensionsV1Api->create_custom_resource_definition: %s\n" % e)

When I run this I am getting a 422. Can you help me find the correct format to create spec and name object?

{"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"CustomResourceDefinition.apiextensions.k8s.io \"\" is invalid: metadata.name: Required value: name or generateName is required","reason":"Invalid","details":{"group":"apiextensions.k8s.io","kind":"CustomResourceDefinition","causes":[{"reason":"FieldValueRequired","message":"Required value: name or generateName is required","field":"metadata.name"}]},"code":422}

Appreciate your help, thank you!
