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):
  File "/Users/robin/mambaforge/envs/sandman/bin/sandman2ctl", line 5, in <module>
    from sandman2.__main__ import main

    scopefunc = options.pop('scopefunc', _app_ctx_stack.__ident_func__)
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?
