[Solved]-My link to manifest.json in index.html works when I run react script 'yarn start', but not when I run 'python3 manage.py runserver'-Reactjs

In urls.py:

from django.urls import re_path

CHANGE: urlpatterns = [ ... path('', TemplateView.as_view(template_name='index.html')]

TO:

urlpatterns = [ ... re_path('.*', TemplateView.as_view(template_name='index.html')]

Had the same error and worked for me.

The same happened to me (blank page and unable to load manifest.json + react build's static files) and I solved the issues thanks to this excellent article

Solution -> assuming your react app (build etc.) are in a folder called frontend at the same level as your django project, in your settings.py file you need to make sure your STATICFILES_DIRS variable is set like below (don't forget the trailing coma as it is a tuple).

STATICFILES_DIRS = (
    os.path.join(os.path.join(BASE_DIR, 'frontend'), 'build', 'static'),
)

I had the same issue and found this Can't get rid of missing manifest.json error
Well, in my case it was browser cache related and swapping to incognito mode was enough.
