Can someone help me identify why my heroku app isn't working when I try to go to it? Here's what the heroku logs --tail says. It's long, but there are errors and I'm not sure what to do. This just randomly happened just after updating a couple things on my heroku app. The app is my web dev portfolio that I'm working on because I just graduated bootcamp.
