Review comment:
Since we have enough information about the error itself, can we improve
the directional information more? For example, we can ask the users to check
`kubectl auth can-i create pod` first. It should be `yes`.
```
Exception in thread "main"
io.fabric8.kubernetes.client.KubernetesClientException: Operation: [create] for
kind: [Pod] with name: [null] in namespace: [default] failed.
