Crash when starting on heroku #3
Description
I can't get the app to start when using the 'Deploy To Heroku' button in the README. After configuring all of the params and starting the app I get the following in the logs:

Am I configuring something wrong? My params look like this:
SLACK_URL="https://hooks.slack.com/services/..."
SLACK_CHANNEL="#general"
APP_URL="https://myapp.herokuapp.com"
