'LocalStack' object has no attribute '__ident_func__' error on launch

After installing sandman2 in a clean environment, I ran it as follows:

sandman2ctl 'sqlite+pysqlite:///chinook.db'

(using the chinook sample database from here).

I get the following error:

Traceback (most recent call last):

AttributeError: 'LocalStack' object has no attribute '__ident_func__'

After some Googling, I found that it might be a version issue with the latest version of werkzeug and the pinned version of flask-sqlalchemy (which was 2.4.0). Upgrading to the latest flask-sqlalchemy (2.5.1 currently) seems to fix it.

Shall I submit a PR to update setup.py to use the latest flask-sqlalchemy, or might be there be more to this that I'm missing?

Any updates here? I still see 2.4 in the code and I think I have the same issue. Only difference is for me it is a _FakeStack object missing that attribute. AttributeError: '_FakeStack' object has no attribute '__ident_func__'

update Flask-SQLAlchemy works for me. ( the solution I looked at StackOverFlow) pip install Flask-SQLAlchemy==2.5.1
