I want this to work whenever there is promise rejection like error in the config file.
I have a code in server.js:
const server = app.listen(process.env.PORT, () => {
console.log(
Server is running on port ${process.env.PORT} in ${process.env.NODE_ENV} mode.
);
});

//Handle unhandled promise rejections
process.on("unhandledRejection", (err) => {
console.log(ERROR : ${err.message});
console.log(Shutting down the server due to Unhandled Promise rejection);
server.close(() => {
process.exit(1);
});
});

this isnt working
