   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: ***************************************************************************************************************************************************************************************************************************************************************.
   Traceback (most recent call last):

   AttributeError: __enter__
   During handling of the above exception, another exception occurred:
   Traceback (most recent call last):

       raise InvalidStatsNameException(
   airflow.exceptions.InvalidStatsNameException: The stat_name (***************************************************************************************************************************************************************************************************************************************************************) has to be less than 250 characters.
   ```
   
   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.
