Similar issue in another project - pallets/flask#4494

Specify this in your requirements.txt as a workaround:

jinja2==3.0.3
flask==1.1.1

For those having this issue is because the last version of Werkzeug are not compatible.
Ref: postmanlabs/httpbin#673

Solved this issue with :
pip install Werkzeug==2.0.3

There are some updates on Jinja2 package. To solve the issue change in the "requirements" the flask version to flask=2.1.0 and re-run the code

Hey @edeng23 can you update requirements? Or should I submit a PR?
