Did you deploy the server? the problem is
"proxy": "http://localhost:5000"
your proxy refer to localhost not the deployed server
And when you deploy react-app and want to connect it with your server you make static.json to refer to your server this is the docs https://github.com/heroku/heroku-buildpack-static.
I notice that you deploy your app (server & client )at once.you should deploy twice one for the server and one for client.
Thank you for the reply!!
Can you please tell me what is this error?? is it the problem for the deployment??
