I'm seeing a very similar error when the stat name is too long (more than
250 characters) in Airflow 2.7.2 (masked due to sensitive data)
```
[2024-03-08, 13:49:12 UTC] {validators.py:101} ERROR - Invalid stat name:

```
What's interesting is that I see the stat name too long exception multiple
times in the logs, but only this instance results in the AttributeError.
