Unable to deploy functions in firebase

Question

I am trying to integrate Razorpay in my nuxt app. For that, I installed razorpay dependency using npm i razorpay

My index.js files starts with

const functions = require('firebase-functions')

const Razorpay = require('razorpay')

const admin = require('firebase-admin')

const crypto = require('crypto')

But after writing the function(basic helloWorld function) and deploying it gave me an error unable to deploy function. But when I commented below line the helloWorld function deployed successfully.

//const Razorpay = require('razorpay')

Again I uncommented above line and it still gives me error unable to deploy.

Version info

Node v12.18.3

Firebase v8.16.2

    "@nuxtjs/axios": "^5.12.2",

Please note that you will need to put the following in the Firebase Cloud Function to integrate the Razorpray:

const Razorpay = require("razorpay");
var key_id = "YOUR_RAZORPAY_KEY_ID";
var key_secret = "YOUR_RAZORPAY_KEY_SECRET";

var instance = new Razorpay({
  key_id: key_id,
  key_secret: key_secret
});

You need to follow the next steps to integrate it:

• Signup for razorpay and grab your Key_Id and Key_Secret from Razorpray
• Integrate the checkout modal from razorpay in the front end to accept the payment details from user.
• Implement Order API in the backend.
• Capture Authorized payments.

Please have a look into the following Medium tutorial for better understanding and this GitHub Repository for a code example.

Regarding Cors error, please make sure the following:

1. Import Cors

const cors = require('cors')({origin: true});

2. Call the cors module at the top of each function as following:

exports.createPayment = functions.https.onRequest(async (req, res) => {
    cors(req, res, () => {
        // your function body here - use the provided req and res from cors
    })
});
