squalou opened a new issue #14029:
URL: https://github.com/apache/superset/issues/14029
When in SQL Lab selecting a schema, then a table in dropdown menu I get an
error instead of colums list.
(Same thing happens when trying to 'add' a table in data/dataset tab)
### Expected results
See the table description on the left pane.
### Actual results
error is displayed, (see screenshot)
and following errors appears in superset logs ;
`TypeError: _get_column_info() missing 1 required positional argument:
'generated' `
More detailed stack :
```python
ERROR:root:_get_column_info() missing 1 required positional argument:
'generated'
