Database list is throwing error , unable to write query in sqllab

See original GitHub issue

A clear and concise description of what the bug is. I am using superset for 4 month now. It was working fine for me but few days back when i tried to open database section it was showing me

Sorry, something went wrong
500 - Internal Server Error

Same with table and user datascoure. Also i am unable to select datasource in sqllab. It is showing nothing there.

Expected results

@villebro using above issue, we finally triaged the issue to records in dbs table where password was not null. As a temporary solution, we have set all passwords to null. I am not sure if this is the right way to go around solving this, do let me know if you have a better solution for this.
