From the logs it looks like the error is coming from line 5 of /app/config/environment.rb, and the actual error is No such file to load -- GiantBomb (LoadError). I’m guessing that you have require 'GiantBomb' at that line, which works locally because you’re on Windows which has a case insensitive file system. Heroku uses Linux which has a case sensitive filesystem, and so it fails as the actual filename is giantbomb (all lower case).

You need to change that line to

require 'giantbomb'
