I recently set up an instance of Tutor running on an EC2, configured certification, added a couple of courses and ran into a 500 error when a student would attempt to look at their certificate. Does anyone have any clue as to why this would be? Below is the stack trace I am getting from the lms_1 Docker container. It almost seems like the user is getting dropped somehow.
