It looks like there's a compatibility issue as all has been removed. Ensure that you are using Flask-SQLAlchemy 3.0.2 or later

Hello, I solved it by installing version 3.0.3 of Flask-SQLAlchemy, in the console: $pip install Flask-SQLAlchemy==3.0.3

I closed the console, run the app.py again and it worked.

I hope it works, regards.
