@Bhavik-ag There's a minute issue which I would like to discuss, on executing dev-env.sh file since we are running backend server in background (detached from the terminal) it causes the port 3333 remains in use even though the terminal has been killed due to which devs will have to either reopen the editor or manually close the port if they want to rerun the server.

[Pratik2026]

One possible solution would be to create a Cleanup function which will close the port whenever the terminal got closed. Let me know if this required.
