An error while deploying to Heroku code=H10

I have looked through similar topics and have so far been unable to resolve my deployment issue. when I’ve deployed it I get an application error. tried to delete it and deploy it again but nothing happened.
But local deployment is working properly.

@BenGitter @chinedu16 Can you please help with this?

Going to hazard a guess here that you develop on Windows.

What you have going on here is a case sensitivity error. Essentially, Heroku is (I believe) running your application in a Unix environment. Your import looks for the Models directory, but you actually have a models directory. On Windows, this doesn’t always make a difference. But on Unix based OSes, it does. Models and models are two different folders.

Update your require statements and you should be good to go. :grin:
