Seems like an error introduced with a new update to CTFd. I’ve tried rebuilding with docker-compose up --force-recreate after git pull but I’m still getting this error.
What should I do to fix the issue?
I’m not sure if --force-recreate does what you want.
You should probably try docker-compose build --no-cache and docker-compose up. If this is still an issue you should check what version of Flask and Werkzeug are being installed. Both are already pinned to a specific version in CTFd so I don’t know what the issue could be.
After doing that, I’m getting this error:

That was the issue! Thanks!
