Hi, I'm trying to get working a developement version in a docker container using base image https://hub.docker.com/_/postgres. I managed to get to flask run but it end it up with the following error

Any suggestions how to resolve the issue?

EDIT: I'm facing the same issue using the Dockerfile from the repo.

@mmsrubar I have a seperate branch (updates-210213: https://github.com/brettkromkamp/contextualise/tree/updates-210213) with a fix for this issue.

Context:

• https://flask-security-too.readthedocs.io/en/stable/changelog.html#version-4-0-0
• https://flask-security-too.readthedocs.io/en/stable/changelog.html#db-migration

Also, keep in mind that I haven't updated and tested Contextualise with Flask 2 (and related dependencies), yet... still on my TODO-list.

Upgrade to Flask 2.0 issue: https://github.com/brettkromkamp/contextualise/issues/109

Thank you! Now I'm able to build the container. Going to get it running and test the app.

Great! Would appreciate if you let me know how it goes :)

@mmsrubar Forgot to mention: you will have to manually uninstall Mistune version 0.84 and install version 2.0.0rc1 (pip install mistune==2.0.0rc1)

[brettkromkamp]

Done.
