grip is not working w/ latest flask and werkzeug versions

[daniel-eichinger-bl]

In the https://github.com/joeyespo/grip/blob/master/requirements.txt file it is stated that grip works with any version of flask or werkzeug higher than 0.10.1 and 0.7.

I tried grip out w/ the latest flask and werkzeug versions installed (v3.0.0) and there is an error thrown:

/opt/hostedtoolcache/Python/3.9.18/x64/bin/grip /home/runner/work/workflow-markdown-to-pdf/workflow-markdown-to-pdf/test/fixtures/example.MD --export ./result/example.html --pass ***

Installing the older flask and werkzeug versions before grip resolves this issue:

pip install werkzeug==2.3.7
pip install flask==2.3.3
pip install grip==4.6.1

Same issue here… but I can't change my flask version because I have a web dev running with the latest flask package. :/

Patched! Just published version 4.6.2. (Upgrade with pip install --upgrade grip)

Thank you for reporting the issue. Re-open if there's other areas still broken with the new release of Flask & Werkzeug 3.0.0.
