Error messages on jinja2, flask, json about marvin HOT 4 CLOSED

@gmleeb I don't recommended editing the code of package dependencies within your python's site-packages folder, as that can lead to unintended dire consequences. Instead you should upgrade or downgrade the packages as needed to resolve the issue. You should be able to resolve this by either upgrading flask>2.1 and jinja2>3.1 or downgrading jinja2<3.1 and/or flask to a lower version. See #791.

I've had the same problem. Upgrading flask and jinja2 has changed the error messages, but there are still incompatibility issues

Here are some screenshots of the different dependency incompatibilities I've been getting when upgrading different packages:
pip -U "flask-jwt-extended>=3.8,<3.9"

pip -U "werkzeug<2.1,>=2.0"

pip -U "flask>2.1,<2.3"
pip -U "werkzeug<2.1,>=2.0"

What versions of these packages do I need to get marvin to run?
Thanks in advance

@gmleeb @Dvorak365 I installed marvin fresh in a new Python 3.10 conda environment and these are the package versions needed to import marvin, that resolves several dependency issues:

werkzeug=2.0.3
packaging=20.9
jinja2=3.0.3
itsdangerous=2.0.1
flask-jwt-extended=3.25.1
flask=1.1.2

That's fixed it, thanks so much for your help!
