Validation fails for CustomResource with array of pointers

按照他说的，

我新建了一个crd，yaml文件内容如下：

apiVersion: apiextensions.k8s.io/v1
kind: CustomResourceDefinition
metadata:
  name: resous.getnull.example.com
spec:
  group: getnull.example.com
  versions:
    - name: v1
      served: true
      storage: true
      schema:
        openAPIV3Schema:
          type: object
          properties:
            spec:
              type: object
              properties:
                allocations:
                  items:
                    nullable: true
                    type: integer
                  type: array
  scope: Namespaced
  names:
    plural: resous
    singular: resou
    kind: Resou

apply -f 这个文件，然后根据这个crd实例化出来一个资源,yaml文件如下：

apiVersion: getnull.example.com/v1
kind: Resou
metadata:
  name: resous-sample
spec:
  allocations: null

这之后执行kubectl edit ipamblocks，直接 :q 退出，就会来到一个新的页面，可以看到这样的报错：

 * <nil>: Invalid value: "The edited file failed validation": [ValidationError(IPAMBlock.spec.allocations): unknown object type "nil" in IPAMBlock.spec.allocations[1]...
