### Superset version
0.999.0dev ` more ./superset/assets/package.json``installed by docker `
### Expected results
I would like to sync superset table columns from datasource table columns because of new column addition in datasource.
but when i press 'Sync columns from datasource' button, I got an error
`sqlalchemy.exc.NoSuchTableError: dwd_gd_trvl_frontdoor_sn_di`
nevertheless, table`dwd_gd_trvl_frontdoor_sn_di` is actually exsited.
