"Internal Server Error" deploying Django app to Heroku

Question

I have a Django app that I'm trying to deploy to Heroku. I've followed the Heroku documentation closely with no real issues. However, after pushing to Heroku, I'm seeing an "internal server error" when I visit the app online. I'm not seeing any obvious errors in the Terminal (below). This is my first time using Heroku so there is probably a rookie mistake somewhere. Help is appreciated.

Answer 1

Can you please provide the output of the command

heroku logs --app YOUR_APP_NAME

and set DEBUG=True on settings.py ?

It seems to be a valid deploy with an application error.

EDIT FROM THE COMMENTS:

South and DjangoExtension.db.fields modules are missing.

Add the missing libraries to the last line of requirements.txt and redeploy your app. Heroku deploy stack will run the command:

pip install -r requirements.txt

And install all the entries on your environment.

Answer 2

The problem might also be that you have misconfigured your wsgi.py.

I was stuck with the same problem. For me the problem was in my_project/wsgi.py . I had setup 3 settings file under my_project/my_project/settings folder and I had configured the necessary configuration under manage.py to detect the setting file but forgot the configuration under my_project/wsgi.py . So resolving this solved the problem for me.
