Response is showing as buffer in reactjs app - node.js

Question

I have created a simple react app. The problem which I'm finding is when I'm hitting the url, in the response, it is showing as buffer, which should not be the case.
My code
index.js
import axios from 'axios';
export const ADD_CART = "ADD_CART";
export const REMOVE_CART = "REMOVE_CART";
export const LOGIN = "LOGIN";
export const BASE_API_URL = "http://localhost:3030";
export function addToCart(item) {
console.log(window.localStorage.getItem('WCToken'))
console.log(window.localStorage.getItem('WCTrustedToken'))
var headers = {
'Content-Type': 'application/json',
'WCToken': window.localStorage.getItem('WCToken'),
'WCTrustedToken': window.localStorage.getItem('WCTrustedToken')
}
axios.post(BASE_API_URL + "/cart", {
orderItem: [
{
productId: item.uniqueID, //working for 12262
quantity: '1'
}
]
}, {headers: headers}).then(res => console.log(res))
.catch(err => console.log(err));
return {
type: ADD_CART,
payload: item
};
}
export function removeFromCart(cartList, id) {
return {
type: REMOVE_CART,
payload: cartList.filter(i => i.uniqueID != id)
};
}
export const login = () => {
return axios.post(BASE_API_URL + "/guestidentity", {}).then(res => {
window.localStorage.setItem("WCToken", res.data.express.WCToken)
window.localStorage.setItem("WCTrustedToken", res.data.express.WCTrustedToken)
return {
type: LOGIN,
payload: {}
}
}).catch(e => {
console.log(e);
return {
type: LOGIN,
payload: {}
}
});
};
server.js
const express = require('express');
const cors = require('cors');
const bodyParser = require('body-parser');
const Client = require('node-rest-client').Client;//import it here
const app = express();
const helmet = require('helmet');
const morgan = require('morgan');
// enhance your app security with Helmet
app.use(helmet());
// use bodyParser to parse application/json content-type
app.use(bodyParser.json());
// log HTTP requests
app.use(morgan('combined'));
app.use(cors());
process.env['NODE_TLS_REJECT_UNAUTHORIZED'] = 0
app.post('/guestidentity',(req, res) => {
console.log("Hello from Server")
var client = new Client();
// direct way
client.post("https://149.129.128.3:5443/wcs/resources/store/1/guestidentity", (data, response) => {
res.send({ express: data });
});
});
app.post('/cart',(req, res) => {
console.log("Hello from Server")
var client = new Client();
// direct way
client.post("https://149.129.128.3:5443/wcs/resources/store/1/cart", (data, response) => {
res.send({ express: data });
});
});
const port = 3030;
app.listen(port, () => console.log(`Server running on port ${port}`));
I dont know where my code is getting wrong and why buffer is showing in response. Can somebody please guide me on this. Or provide me an insight how to troubleshoot this issue.

You might need to config your client as to parse response as JSON.
var options = {
mimetypes: {
json: ["application/json", "application/my-custom-content-type-for-json;charset=utf-8"]
}
};
var client = new Client(options);
