URL: https://github.com/apache/airflow/issues/26492#issuecomment-1251078527
From the discussion:
Sorry if not clear, but this already happened in 2.4.0, which I installed today (It was fine on 2.3.3 and before).
Running on Python 3.10.5.
This is the message from the web UI:
This is the relevant log from the remote celery worker when the web UI requests the task log:
```

```
Looks like the `request.view_args` is `None` in the validation function. Don't know whether it's the root cause though.
Do you need any additional logs?
