I am trying to deploy an project manager app to heroku. It's running working locally. I am following the tutorial https://www.codementor.io/@jamesezechukwu/how-to-deploy-django-app-on-heroku-dtsee04d4 to deploy me app. I don't know where is the error and how to fix so hope you can help. NotADirectoryError at /, saying [Errno 20] Not a directory: '/app/myProjectManager/settings.py/staticfiles/staticfiles.json'

Here is some of my backend code:
