werkzeug.urls Error when following along with the "Webapps with Docker" part of the Tutorial

Received this error when trying to follow along with the catnip application steps in the Docker Tutorial for Beginners guide

$ docker run -p 8888:5000 yourusername/catnip
Traceback (most recent call last):

    from werkzeug.urls import url_quote
ImportError: cannot import name 'url_quote' from 'werkzeug.urls' (/usr/local/lib/python3.8/site-packages/werkzeug/urls.py)

After I did some digging setting Werkzeug==2.2.2 in requirements.txt was able to make it work.

Not sure if that is an appropriate fix, or just a workaround. I wanted to submit it just in case other users are running in to the same problem.
