Issue with SQLAlchemy 1.4.0

[sonicnkt]

There is a issue with SQLAlchemy 1.4.0 which is automatically installed as a dependency of Flask-SQLAlchemy in the requirements.txt.

It leads to the following issue when running the app:

sa_url.database = os.path.join(app.root_path, sa_url.database)
AttributeError: can't set attribute

It can easily be fixed for the moment by manually adding SQLAlchemy==1.3.23 to requirements.txt.
