I have tried doing heroku run bash and running require('./models/Comic') from node session in app and require('../models/Comic') from within a subdirectory of /app/routes/ to test that require works.

The only instances of the require for Comic are in the three routes within the routes folder. They all have the exact same var myVar = require('../models/Comic'); .

Answer 1

I figured out that heroku :

a) Takes the info from Git. Even though I had made case changes in my local files and pushed to Git, the case wasn't changed. Then when the file was required on heroku which uses Linux, it could not find the file.

b) Only changing the name of the file from heroku run bash didn't seem to have any affect. I am assuming I wasn't doing some sort of deployment step or that I needed to do something extra (I tried heroku restart but no dice).

Hope this can help someone else.
