Firebase Cloud function request.body empty or undefined - node.js

Question

const functions = require("firebase-functions");
const Razorpay = require("razorpay");
const cors = require("cors")({origin: true});
exports.razorpayverification = functions.https.onRequest((req, res) => {
try {
const name = JSON.stringify(req.body);
console.log(req.body, name);
res.status(200).json({status: "ok"});
// I need req.body.amount value. req.body is empty. but JSON.stringify(req.body) contains all the data.
} catch (error) {
res.status(400).json({error: "JSON error"});
res.end();
}
});
I am using the above cloud function and receiving payment data from Razorpay webhooks. In my console.log I have called req.body and name (const name = JSON.stringify(req.body);). name returns the data in string format and contains all information like orderid, payment id, amount etc but req.body is empty or undefined. I tried enclosing the above within cors but still the same result. Kindly let me know how to read req.body. I need to read req.body.amount.
Output:
req.body:
{
name: {"entity":"event","account_id":"acc_IvsP3zm1EoP7me","event":"payment.captured","contains":["payment"],"payload":{"payment":{"entity":{"id":"pay_J9fXFPd7T9uWo5","entity":"payment","amount":1000,"currency":"INR","status":"captured","order_id":"order_J9fWySTzmrenBl","invoice_id":null,"international":false,"method":"card","amount_refunded":0,"refund_status":null,"captured":true,"description":"Recharge","card_id":"card_J9fXFSITSAyVdB","card":{"id":"card_J9fXFSITSAyVdB","entity":"card","name":"k","last4":"1111","network":"Visa","type":"debit","issuer":null,"international":false,"emi":false,"sub_type":"consumer","token_iin":null},"bank":null,"wallet":null,"vpa":null,"email":"test#test.com","contact":"[phone]","notes":{"key1":"otzo","key2":"recharge","address":"Razorpay Corporate Office"},"fee":20,"tax":0,"error_code":null,"error_description":null,"error_source":null,"error_step":null,"error_reason":null,"acquirer_data":{"auth_code":"213319"},"created_at":1647850380}}},"created_at":1647850385}
As shown req.body returns only the open curly braces and nothing after that. name returns all the data.

Not sure this is the correct answer but my code was executing properly and I was receiving the res.body. But issue lies in the console.log which did not display. if it is a multi-level object firebase cloud function is not displaying properly. Below is the Razorpays Payments Sample Payload. res.body displays only open end curly bracket. res.body.payload created log with all the details under the payload section. Again here firebase cloud function displays each and every field as a separate log.
