AttributeError: directory after update to 4.1.0

Hello :)

I'm having an issue since upgrading to 4.1.0, now every time I run flask db upgrade or flask db heads I get the following error:

Traceback (most recent call last):

AttributeError: directory

When running flask db upgrade -d migrations I get pretty much the same trace but with AttributeError: x_arg

I'm using SQLAlchemy 1.4.54, Flask 2.1.3, Flask-SQLAlchemy 2.5.1 - could it be an incompabitility ?

Downgrading to previous version fixes the problem

Thanks for the help :) !

You are using a recent version of Flask-Migrate with very old versions of Flask (3 years old) and Flask-SQLAlchemy (4 years old). It is possible that something in Flask or Flask-SQLAlchemy or SQLAlchemy was different in those old versions. Is there any reason why you want to use the latest Flask-Migrate but stay on such old versions for your other dependencies?

Thank you for your reply and your time!

I though it could be a widespread issue but that doesnt seem to be. I'll look into upgrading those packages and see if that fixes the issue,

Thank you for your work :) !
