Crash after login - Githubissues

I was trying to run online-text-flow-server in a docker container (fresh build from the current master, using the Dockerfile in repo). I access the application at localhost:5002/textflow in a browser on localhost, I see the login page, but after I try to login (with the default elitr/elitr login/pw), it crashes -- see the logs. The login page is inacessible after the crash.

~/r/online-text-flow on master ◦ docker run -it --rm -p 5002:5002 online-text-flow:latest /bin/sh

The app was installed with python3 ./setup.py install. client and events seems to work just fine. Do you know where the error could be? It doesn't seem like the error is in the code itself, but rather in the libraries used. I see the lib versions are not pinned -- perhaps one of them got updated recently and now it's broken? I've looked at Hypercorn's and Quart's issue tracker, but nothing relevant. Could you please provide the lib versions you're using?
