reactjs - Can't refresh page in React-django app deployed in Heroku

Question

I'm trying to deploy an application that I have made using the Heroku platform.

I have followed this tutorial to deploy the application and everything seems to work well until the page is refreshed (whether I refresh it manually, or the internal code has to refresh it). Everything works fine on my local computer. The error:

Not Found

The requested resource was not found on this server.

is displayed on the deployed app when I try to refresh the page. I'm guessing it's a problem with my "views.py" file or "settings.py" file. Here there are:

## views.py
from django.views.generic import TemplateView
from django.views.decorators.cache import never_cache

# Serve Single Page Application
index = never_cache(TemplateView.as_view(template_name='index.html'))

I would really appreciate the help. Thanks.
