Hi @apoorvashirikan , welcome to the forums!
Try switching the port to another number and try again.

Hi, I tried with several port numbers. It doesn’t seem to work. For reference, this is the error I’m getting
node:events:492
throw er; // Unhandled ‘error’ event
^
Error: listen EADDRINUSE: address already in use :::5000

Try running lsof -i tcp:5000 in the shell to see which process is using port 5000.

thanks everyone. The error was because I was already running the application on shell using (npm start) and then was trying to run again using the “Run” option. :sweat_smile: thanks again everyone for the assistance !!
