## Why are these changes needed?
I recently used the `ray job submit` CLI and got this confused error
message
```sh
TypeError: 'NoneType' object is not callable
```

<!-- Please give a short summary of the change and the problem this
solves. -->

As the ray-project#41604 mentioned, it need a proper error message instead of
raising `NoneType` error.
