OK, so I deploying a very basic app to Heroku. I’ve followed tutorial to the letter. Everything about this deployment was textbook, but when I open the site on Heroku, I get the frustratingly vague message "We’re sorry, but something went wrong."

When I do "heroku ps" it says:

    Process  State       Command                               
    -------  ----------  ------------------------------------  
    web.1    up for 13m  bundle exec rails server thin -p $..

When I run "heroku logs" I get the usual deprecation messages and then the text below. But I don’t see any red flags in these logs that would cause the app to crash. Am I missing something?

    The problem was that I wasn’t showing enough records. Once I ran heroku logs -n 2000 (or some other large number), it showed me the problem that was right at the start of things
