[GitHub] [incubator-superset] iercan opened a new issue #12155: Getting error while trying to connect mongo via drill
iercan opened a new issue #12155:
URL: https://github.com/apache/incubator-superset/issues/12155
Hi. I configured drill so that I can read mongodb via superset. I'm getting error when sqllab try to get tables.
### Expected results
Send sql requests successfully to mongo by using sql_lab
### Actual results
Superset throws below error.
```

#### How to reproduce the bug
1. Configure drill so that it can request mongodb
2. Add drill datasource to superset
3. Try to send request from sqllab
### Environment
