```
**- Strange to see it works with preset but not on my customized container
deployment.**
Additional points:
I've tested connection via both flight and non-flight based mode in dremio.
```dremio://{USER}:{PASS}@{IP}:31010/dremio```
and
```dremio+flight://{USER}:{PASS}@{IP}:31010/dremio```
### Environment
- browser type and version:
- superset version: `2.0.0`
- python version: `3.7`
