I've been working on setting up a Stripe webhook in my NextJS app to write data to Firebase Firestore, but for some reason, stripe.webhook.constructEvent is showing up as undefined even though everything seems to be properly configured.
I'm using the following command with Stripe CLI:
stripe listen --forward-to localhost:3000/api/webhook
The output I'm getting is:
2022-12-20 16:57:18 --> charge.succeeded [evt_3MH8BsL1z8EG1fYg1HgxX6Fm]
2022-12-20 16:57:18 --> payment_intent.succeeded [evt_3MH8BsL1z8EG1fYg1ExIxxZ7]
2022-12-20 16:57:18 --> checkout.session.completed [evt_1MH8BuL1z8EG1fYgo2lLPZkC]
2022-12-20 16:57:18 --> payment_intent.created [evt_3MH8BsL1z8EG1fYg1ezapckU]

2022-12-20 16:57:18 <-- [400] POST http://localhost:3000/api/webhook [evt_3MH8BsL1z8EG1fYg1ezapckU]
However, in the app console, I'm encountering the following errors:
Error Cannot read properties of undefined (reading 'constructEvent')
Error Cannot read properties of undefined (reading 'constructEvent')
Error Cannot read properties of undefined (reading 'constructEvent')
Error Cannot read properties of undefined (reading 'constructEvent')
Here's the code from webhook.js:
import { buffer } from "micro";
import * as admin from "firebase-admin";
const serviceAccount = require("../../../credentials.json");
const app = !admin.apps.length
? admin.initializeApp({
credentials: admin.credential.cert(serviceAccount),
})
: admin.app();
//connect to stripe
const stripe = require("stripe")(process.env.STRIPE_SECRET_KEY);
const endpointSecret = process.env.SIGNING_SECRET;
const fulfillOrder = async (session) => {
// Code omitted for brevity
};
export default async (req, res) => {
// Code omitted for brevity
};
export const config = {
api: {
bodyParser: false,
externalResolver: true,
},
};
I have confirmed that none of the arguments for constructEvent are empty, yet it still returns as UNDEFINED. I'm running out of ideas and would appreciate any help or insights. Thank you.
