MERN app on Heroku- route problems

I have problems with my MERN app :frowning: it starts at localhost:3000/React_Portfolio but i don’t have anything on this route. So i get 404 page.
Localy app is working but I want it to start at localhost:3000.

  • After npm run dev I get this message :
[1] ℹ 「wds」: Project is running at http://172.19.64.18/
[1] ℹ 「wds」: webpack output is served from /React_Portfolio
[1] ℹ 「wds」: Content not from webpack is served from /app/client/public
[1] ℹ 「wds」: 404s will fallback to /React_Portfolio/
  • I checked all files, React_Portfolio does not appear anywhere. Where should I look for it?

  • After deploy at Heroku there is this damp-cove-21795.herokuapp.com/

  • When i refresh it heroku logs :

at=info method=GET path="/React_Portfolio/favicon.ico" host=damp-cove-21795.herokuapp.com request_id=7e5ff2e5-4629-4f2c-8fb9-4e6b4d7f444b fwd="31.0.69.41" dyno=web.1 connect=1ms service=5ms status=200 bytes=2997 protocol=https

Git repo github.com/Ecuki/cv_2 Sorry for that mess I made.

Ok I get that. Its because i have set homepage in my json file.
