<p>I'm trying to use Stripe payments in my node.js app to sell products to users on whatsapp. </p> <p>I installed the stripe extension: stripe/firestore-stripe-payments@0.3.3 and followed the instructions in the documentation: </p> <pre class="brush:php;toolbar:false;">const docRef = await db .collection('customers') .doc(currentUser.uid) .collection('checkout_sessions') .add({ price: 'price_1GqIC8HYgolSxxxxxxxxx', success_url: window.location.origin, cancel_url: window.location.origin, }); // Wait for the extension to attach CheckoutSession docRef.onSnapshot((snap) => { const { error, url } = snap.data(); if (error) { // Show the error to the client and check the cloud function logs in the Firebase console. alert(`An error occurred: ${error.message}`); } if (url) { // We have a Stripe Checkout URL, let's redirect. window.location.assign(url); } });</pre> <p>I receive the following error in the cloud console: </p> <p><code>❗️[Error]: Failed to create a Checkout session for document [maxxxxxxxxxA]: The provided identifier does not have a corresponding user record. </code></p> <p>I found that I need to use the userId from Firebase Authentication, but since I'm running my service in a function (backend server), there is no client/user in the auth. </p> <p>Is there another way to create (individual) stripe checkout links? Is there a way to use Firebase Authentication without a client? </p> <p>Thanks in advance. </p> <p>I tried using auth,</p> <pre class="brush:php;toolbar:false;">import { getAuth } from "firebase/auth"; const auth = getAuth(); const user = auth.currentUser;</pre> <p>But I get the following error: <code>FirebaseError: Firebase: Options need to be provided when not deploying to hosting via source. (app/no-options)</code></p> <p>I tried this: https://stackoverflow.com/a/74732162/21612440</p> <p>and got<code>TypeError: Cannot read property 'getProvider' of undefined (read 'getProvider')</code></p>
