I just upgraded an instance of gitlab-ce from version 13.3.9 to version 13.4.7, and am now getting a 500 error when a user tries to log in.
I looked in the logs using sudo gitlab-ctl tail, and this is the traceback:

I searched online but it doesn’t seem anyone has had this particular error. Already logged-in users can use it fine as long as they don’t log out, and git pull and clone and such still work. Just the web app login is broken.
