firebase deploy functions failed due to bug in the user code

Question

I am stuck to firebase deploy the functions, the function failed on loading user code. but I can not find anything wrong with the code as shown below. i thought I should add the admin service account, but still have the same error when it goes to the step node.js 16 function api. (I have no problem to fetch the api when use the firebase emulators but failed to fetch the api deploy the app and functions)

const functions = require("firebase-functions");
const express=require("express");
const cors=require("cors");
require('dotenv').config({ path: './.env' });
//API
const stripeAPI = require('stripe')(process.env.REACT_APP_SECRET_KEY);
//App config
const app=express();
var admin = require("firebase-admin");

var serviceAccount = require("../serviceAccountKey.json");

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount)
});
//middlewares
app.use(cors({origin: true}));
app.use(express.json());

async function createCheckoutSession(req, res) {
  const domainUrl = process.env.WEB_APP_URL;
  const { line_items, customer_email } = req.body;
  // check req body has line items and email
  if (!line_items || !customer_email) {
    return res.status(400).json({ error: 'missing required session parameters' });
  }
  let session; 
  try {
    session = await stripeAPI.checkout.sessions.create({
      payment_method_types: ['card'],
      mode: 'payment',
      line_items,
      customer_email,
      success_url: `${domainUrl}/success?session_id={CHECKOUT_SESSION_ID}`,
      cancel_url: `${domainUrl}/canceled`,
      shipping_address_collection: { allowed_countries: ['GB', 'US'] }
    }); 
    res.status(200).json({ sessionId: session.id, });
  } catch (error) {
    console.log(error);
    res.status(400).json({ error: 'an error occured, unable to create session'});
  }
}
app.get('/',(req, res)=>res.send('Hello World!'));
app.post('/create-checkout-session', createCheckoutSession);

exports.api=functions.https.onRequest(app);

Can you share your package.json file as well? What do the logs tell you more? — W.S.

W.S.: Thank you for replying my question. I editted my post adding package.json in the functions folder, and run npm install firebase-functions@latest firebase-admin@latest --save npm install -g firebase-tools. However, the same error still came out. I also add the firebase debug log in my question. I still do not know where is wrong. — Grace

You have declared dotenv as devDependency but are using it in the code. When this is deployed to firebase all the devDependencies will be ignored unless otherwise specified. Try to moving it to dependencies.

Edit: The issue was due to service account location.

Thank you Naveen, but the same error still shows up after I move the dotenv to dependencies. one thing I feel weird about my .env file is that I set domainUrl=challenge-bcf4d.web.app, a red curve line under ":" and error hint ";" expected. ts(1005). I am not sure it really matters to deploy the functions, in my package.json script, should I change "start": "npm run shell" to "nodemon index.js"? all is my speculation, I have no solid clue how to debug the error and stuck with it for a long time

I have not problem to firebase emulator and fetch the api "localhost:5001/challenge-bcf4d/us-central1/api", but fail to deploy to fetch "us-central1-challenge-bcf4d.cloudfunctions.net/api"

Naveen Kulkarni Over a year ago

The ts thing is probably fine because the same code works in emulator. Also don't use nodemon index.js. Try changing the start to node index.js. Also we need logs to debug this. Can you see if you can find anything in stackdrive? Or try deployment the firebase function using gcloud from your machine even that should print logs about the error.

@Grace Can you also share your folder structure?

Grace Over a year ago

Naveen, I just add a snapshot of the functions folder structure at the bottom of the posted question. Thanks!

I had the same issue because I had the firebase dependency in my node_modules folder but it wasn't listed under my dependencies in package.json.
