Production build

in video 3 and after making production build, Superman value is still set, opposite to what is showed in the course, that it must be “undefined”, anybody know how is it possible?

In the terminal, navigate to your project directory and run “ls -a”. What files do you see there that start with .env…?


You’re running your production build with ‘serve -s build’ and not ‘npm start’, correct?

yes and I did it several times, but I got always opposite results comparing with course, so I can not figure out, where the problem lies !
