Error while running demo

Followed exact steps from quick start demo and getting this error (windows and ubuntu the same error)

Traceback (most recent call last):

Hi, I will be checking this.

[pythononwheels]

This is due to some major changes in sqlalchemy 2.0.
As a quick fix: in your virtual environment:

pip uninstall sqlalchemy

pip install sqlalchemy==1.4.46

pip freeze

should show you the correct version of sqlalchemy now.

I will adapt the binding in the package.
Thanks for the info !

[pythononwheels]

can you check if the sqlqlchemy version was causing the issue ?

Ok, server.py runs finally after downgrading sqlalchemy. Thanks!
