**Apache Airflow version**: 2.0.0
**Kubernetes version (if you are using kubernetes)** (use `kubectl version`): N/A
**Environment**:
- **Cloud provider or hardware configuration**: docker-compose
- **OS** (e.g. from /etc/os-release): Docker `apache/airflow` `sha256:b4f957bef5a54ca0d781ae1431d8485f125f0b5d18f3bc7e0416c46e617db265`
- **Kernel** (e.g. `uname -a`): Linux c697ae3a0397 5.4.0-58-generic #64~18.04.1-Ubuntu SMP Wed Dec 9 17:11:11 UTC 2020 x86_64 GNU/Linux
- **Install tools**: docker
- **Others**:
**What happened**:
When an event that does not include a DAG is logged in the UI, this event lists the DAG ID as "None". This "None" is treated as an actual DAG ID with a link, which throws an error if clicked.
```
Something bad has happened.
Please consider letting us know by creating a bug report using GitHub.

<!-- (please include exact error messages if you can) -->
**What you expected to happen**:
I expected `None` to not be a link or have it link to some sort of error page. Instead it throws an error.
**How to reproduce it**:
Run a CLI command such as `airflow dags list`, then go to `/log/list/` in the web UI, and click on the `None` *Dag Id* for the logged event for the command.
**Anything else we need to know**:
This problem appears to occur every time.
