TypeError: cannot create weak reference to 'LocalProxy' object

[DarkRedman]

Once I setup the venv and installed the requirements and start the program, I get this error when going trough the api page :

TypeError: cannot create weak reference to 'LocalProxy' object

I tried to change the line 34 in db.py as this :

with current_app.app_context():
    db = LocalProxy(get_db)

But it doesn't solve the problem and still get this error :

RuntimeError: Working outside of application context.

Which means the app_context() function isn't even working.
