I found a post on stackoverflow solution regarding the proxy issue, that says to create a separate setupProxy.js file and apply proxy in below way const proxy = require('http-proxy-middleware'); module.exports = function(app) { app.use(proxy('/auth/google', { target: 'http://localhost:5000' }, "/api/*", { "target": "http://localhost:5000" } )); } and delete the proxy from client/package.json, But this remains a temprory solution, and often the error appears regular

Issue 3: http://localhost:5000/api/current_user the page remains totally blank, no current user is shown

first error white list your ip address from your mongodb cluster. The setting is under security

Yes the setupProxy.js is the accepted solution. there is a text document update inside of the course

Big THANKS: It really worked. But now I'm facing a problem in Heroku deployment, and heroku logs shows chunk of errors, and on heroku server it shows: Cannot GET /

can you post a screenshot of the errors Heroku is showing you?

So I don't see the repo under your account, is it a private one?

I took a look at the error messages, it looks like something under the options to build out the create-react-app is failing
