Error : `ModuleNotFoundError: No module named 'flask.scaffold'`

[Schefflera-Arboricola]

Description I was getting the following error and I wanted some help because I was able to host the website locally using docker 3 months ago and I didn't make any major changes since. Could you please refer/guide me on how I should approach debugging this?

Additional context

Thank you :)

The issue is caused by incompatibility currently between flask>=3.0.0 and flask-restx, see https://github.com/python-restx/flask-restx/issues/566

Either downgrade to flask<3.0.0 or use flask-restx==1.2.0 which introduced a dependency to prevent this from happening.

That being said, I've hopefully got a bit of spare time this week to get everything merged and make flask-restx compatible again!

Thanks @peter-doggart! It worked!
