Trying to set up using code v4, but get error 1002

```
site-packages/roborock/web_api.py", line 339, in code_login_v4
    raise RoborockException(f"{login_response.get('msg')} - response code: {response_code}")
roborock.exceptions.RoborockException: parameter error - response code: 1002
```

I haven't seen that error code before.  Do you know what it means?
