kind List not found in v1 groupversion

[jplitza]

What happened?

Validating a manifest containing a List failed with the error message:

failed to retrieve validator: kind List not found in v1 groupversion

What did you expect to happen?

I expect validation to succeed for every manifest I can apply without errors via kubectl create -f. Since Lists are understood by kubectl create, I expect them to be understood by kubectl validate.

How can we reproduce it (as minimally and precisely as possible)?

Minimal (kubectl create complains there is nothing to apply, though):

apiVersion: v1
kind: List
items: []

A bit more extensive (actually works with kubectl create):

apiVersion: v1
metadata:
  namespace: default
kind: List
items:
- apiVersion: v1
  kind: ConfigMap
  metadata:
    name: test
  data:
    test: "foo"

Anything else we need to know?
