Error when deplyoing Django-React app to Heroku

I'm deploying my Django-backend, React-frontend app to Heroku and when running git push heroku master I'm running into a weird error:

Could not find a required file.
Name: index.html Searched in: /tmp/build_7abd977a/public

This is my project frontend structure:

As you can see the index.html file is there inside the public folder. There is also a build folder that has no public folder inside it but it does also have the same index.html but compressed. Maybe thats the one its looking for?
