How to check path of a file/script in Beanstalk?

I am trying to deploy a Django REST framework API and ReactJS app to AWS Beanstalk.

The API works if I use Postman.

When I try to load the main.js I get the error:

http://django-env1.eba-ispw2cg9.us-west-2.elasticbeanstalk.com/static/frontend/main.js
404 Not Found

I have moved the static/frontend folder to the main folder.

How can I check the directory structure and where exactly to put the static folder so that the above URL will find it and load?
