kubecfg can't delete clusterrole from jsonnet

[jjo]

With below jsonnet for a simple clusterrole:

$ cat kubecfg-clusterrole-foo.jsonnet
local k = import "ksonnet.beta.1/k.libsonnet";
local objectMeta = k.core.v1.objectMeta;

local controller_roles = [{
  apiGroups: ['core'],
  resources: ['pods'],
  verbs: ['list'],
}];

local clusterRole(name, rules) = {
    apiVersion: "rbac.authorization.k8s.io/v1beta1",
    kind: "ClusterRole",
    metadata: objectMeta.name(name),
    rules: rules,
};

local controllerClusterRole = clusterRole("foo", controller_roles);

{
  controllerClusterRole: controllerClusterRole,
}

, doing update+delete fails with:

$ kubecfg -v=1 update kubecfg-clusterrole-foo.jsonnet 
INFO  Updating ClusterRole/foo
INFO  Creating non-existent ClusterRole/foo
$ kubecfg -v=1 delete kubecfg-clusterrole-foo.jsonnet 
INFO  Deleting ClusterRole/foo
FATAL Error deleting ClusterRole/foo:  "" is invalid: []: Invalid value: v1.DeleteOptions{TypeMeta:v1.TypeMeta{Kind:"", APIVersion:""}, GracePeriodSeconds:(*int64)(nil), Preconditions:(*v1.Preconditions)(nil), OrphanDependents:(*bool)(0xc426cd5aee), PropagationPolicy:(*v1.DeletionPropagation)(0xc426cd5af0)}: OrphanDependents and DeletionPropagation cannot be both set

# while kubectl CLI works ok:
$ kubectl delete clusterrole foo 
clusterrole "foo" deleted
