problem with werkzeug and flask in nginx-flask-mysql

[iyad-obeid]

There is some sort of version / dependency issue with Flask and Werkzeug:

cd nginx-flask-mysql
docker compose up

Crashes with the following trace, over and over:

nginx-flask-mysql-backend-1  | Traceback (most recent call last):

This is a version problem. I had the same. I haven't looked much into it to understand the real issue, however, I found that those two versions work together. :

Werkzeug==2.3.7
flask==2.2.2

That did the trick! You might consider making that change to the repo, it would be really helpful. Thanks!
