Thanks for pointing out the 404 error. You just need to add the following code inside the server/index.js file before the app.listen call

app.get('*', (req, res) => {
  res.sendFile(path.join(__dirname, '..', 'build', 'index.html'));
});
Enter fullscreen mode Exit fullscreen mode

I have updated the article with these instructions at the end of the article. So please check that out.

Regarding the favicon error, I'm not able to reproduce that. You might not have the favicon.ico file in the public directory so that might have caused that issue. But that is fine, Its not required for the application.
