list_api_service: ValueError: Invalid value for `service`, must not be `None`

Hello, I try to get apiservice using in python doing:

config.load_kube_config(kubectl_config_full_path)
api_instance = client.ApiregistrationV1Api()
response = api_instance.list_api_service()
print("Api services: " + str(response))

but I get the following error:

ValueError: Invalid value for service, must not be None

I have a AWS EKS 1.15 as Kubernetes Master. Python 3.6.8. python kubernetes client 10.0.0 Ubuntu 16.04.6 LTS

Update: I’ve tested it with python kubernetes client 11.0.0 and I get the same error

Looks like this is another occurrence of https://github.com/kubernetes-client/gen/issues/52 and has been fixed by https://github.com/kubernetes/kubernetes/pull/85728 in Kubernetes 1.18. Kubernetes sometimes incorrectly restricts a field to be required but the apiserver may omits the field in real responses. These responses break the generated clients since the generated client-side validation expects the required field to exist.

For now the workaround is either to avoid de-serializing the response so the client-side validation doesn’t kick in, or to remove the client-side validation if you have access to your local module code. Once we cut a new release with the 1.18 openapi spec, the generated client won’t expect the field to be required.

@MoShitrit thanks for the workaround, it fits ok for me. Regards.
