I am experiencing this in Superset 6.0.0. When I try to load the table
metadata in SQL Lab (it doesn't display), I get the same error in the UI `An
error occurred while fetching table metadata. Please contact your
administrator.` and this in the logs:
```

@DataStrategistTeam can you test whether you still experience this in 6.0.0?
