Below is my gateway.js file

const express = require('express');
const app = express();
const bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: true }));
const PORT = 9999;
const { createProxyMiddleware } = require('http-proxy-middleware');
app.use('/flight', createProxyMiddleware({
    target: 'http://localhost:9998',
    changeOrigin: true,
    preserveBody: true,
    timeout: 10000

const startServer = async () => {
    app.listen(PORT, () => {
        console.log(`gateway server is running on port ${PORT}`);


I am making call from post man to this above file which i am running on port 9999 and this should redirect to this below code

This below is code of index.js file
const express = require('express');
const bodyParser = require('body-parser');
const PORT = 9998;
const app = express();
const Cors = require('cors');
app.use(bodyParser.urlencoded({ extended: true }));

app.use('/flight', async (req, res) => {
    return res.status(200).json({
        data: req.body,
        message: "reached the flight index"

const setupAndStartServer = async () => {
    app.listen(PORT, async () => {
        console.log(`flight server started at port number : ${PORT}`);


when I am sending something in x www form urlencoded the request is not recieved but when I am not sending anything in the request body then I am getting the desired output
    "data": {},
    "message": "reached the flight index"

In x-www-form-urlencoded i am only sending key ->name ,value ->someName

why when sending the body the above code is not working
I have made a get/post/patch request through postman on -> localhost:9999/flight

also when body is sent in request through postman it continues to show that sending request and after few minutes this below error got printed on the index.js console

flight server started at port number : 9998
BadRequestError: request aborted

Not sure if this is relevant or not but all the documentation I saw for express endpoints suggested using app.get('/path', (req, res) => {}) and'/path', (req, res) => {}) to define the endpoints?
