Firebase Cloud Functions CORS Error for Stripe API
this route gives me the following CORS error
has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
The error is related to the async and await code but dont know how to resolve with firebase.
import * as functions from 'firebase-functions'; const express = require('express'); const cors = require('cors'); const stripe = require("stripe")("sk_test_0KLpj4ajduVN3s3iDqtji3fs"); const app = express(); app.use(cors({ origin: true })); app.use(express.json()); const calculateOrderAmount = (items: any) => { return items / 100; }; app.post("/create-payment-intent", async (req: any, res: any) => { const { items } = req.body; const paymentIntent = await stripe.paymentIntents.create({ amount: calculateOrderAmount(items), currency: "usd" }); res.send({ clientSecret: paymentIntent }); }); exports.payments = functions.https.onRequest(app);
