@rvnbrg Jinja is a dependency of Flask and Flask V1.X.X uses the escape module from Jinja, however recently support for the escape module was dropped in newer versions of Jinja
To fix this issue, simply update to the newer version of Flask V2.X.X in your requirements.txt where Flask no longer uses the escape module from Jinja.
I see there is a requirements.txt where the version of Flask is specified. Maybe updating that to 2.1.1, which is the recommended version that no longer has a dependency on escape
would resolve this.
This is all just guessing. Was trying to figure out how this module hangs together. 🫣
