URL: https://github.com/apache/superset/issues/23541
I'm trying to connect Superset to a DuckDB database file. I receive the
following error:
```
SupersetErrorsException
Traceback (most recent call last):
File "/app/superset/databases/commands/test_connection.py", line 120, in

(Background on this error at: http://sqlalche.me/e/13/dbapi)
The above exception was the direct cause of the following exception:

#### How to reproduce the bug
1. Go to Data => Databases
2. Click `+ Database` and Select DuckDB from the dropdown list
3. Enter 'duckdb:///app/tutorial.db'
4. See error popup : An error occurred while creating databases: Connection

Also, when creating the engine with the superset CLI
```superset set_database_uri -d duckdb -u duckdb:///app/tutorial.duckdb```
The same None Error Type appears.
