Hi there, I just tried setting up this app in Heroku but it gives an Internal Server Error whenever the Github webhook is triggered. Looking into the log files it the culprit appears to be NoMethodError - undefined method 'end_with?' for nil:NilClass which comes from server.rb. I have not modified any of the commit-hawk files, this is an exact clone of the current version.
Here's the full stack trace:
