Try running your app using a different port or kill the process in the current port 5000

To kill a task in windows

//get process running in port 5000

netstat -ano | findstr :5000 

//enter your pid and force kill
//replace <pID> with your process id

taskkill /PID <pID> /F

Use try/catch:

try {
    app.use(cont);
} catch(er) {
    console.log(er);
}

Also note that port 5000 is already in use (EADDRINUSE) - try changing your port to something else.

It seems like something already uses 5000 port.

If you use *nix based OS, you can get list of processes like this:

netstat -tulpn | grep 5000

and then, kill particular process:

kill -9 PID
