### Bug description
Hi Team,
We are facing the below error while connecting to Apache Druid from the
Superset Database connections option on UI.
Traceback (most recent call last):
File
"/usr/mware/vsass/lib64/python3.9/site-packages/superset/commands/database/test_connection.py",
line 170, in run
raise DBAPIError(ex_str or None, None, None)
sqlalchemy.exc.DBAPIError: (builtins.NoneType) None
(Background on this error at: https://sqlalche.me/e/14/dbapi)
**superset.exceptions.SupersetErrorsException:
[SupersetError(message='(builtins.NoneType) None\n(Background on this error at:
https://sqlalche.me/e/14/dbapi)',
error_type=<SupersetErrorType.GENERIC_DB_ENGINE_ERROR:
'GENERIC_DB_ENGINE_ERROR'>, level=<ErrorLevel.ERROR: 'error'>,
extra={'engine_name': 'Apache Druid', 'issue_codes': [{'code': 1002, 'message':
'Issue 1002 - The database returned an unexpected error.'}]})]**
We manually tried a basic Python script for connection for Druid UI from the
Superset server and "Connection is successful" indicates the Druid URL is
working.
Is there any issue with the newer version of the superset? Appreciate your
help and support.
For your information, below are the installed versions
**Apache Superset 4.1.0
Apache Druid 27.0.0
Python 3.9
PyDruid 0.6.9**
