Difficulty bootstrapping in heroku

[sihil]

I've struggled to get the application running on Heroku. Despite successfully installing the application on Heroku, I'm unable to run the heroku run bundle exec rake db:migrate command.

Initially I thought it might be because I'd inadvertently deployed on heroku-16 rather than cedar-14. However, I switched that out and the problem persists. I've also tried reseting the DB to see if it had got into a bad state.

I believe I've followed the instructions correctly, but not having much Heroku or Rails experience I'm not sure if I've made a mistake or if something has broken in the bootstrap process. Any assistance is greatly appreciated!

The error I see is a IndexError: string not matched with the full stack trace being:

I've just noticed that GitHub stopped using boxen some time ago and many people are moving away in favour of other options. I'm off to review them :)
