React/Node: Integration error encountered when subscribing using Trial_period_days
I have defined a product in Stripe that I want to set up as a 7 day free trial and then charge the customer (unless they cancel beforehand)
Using a custom Nodejs function via Firebase - I get the following error:
Missing value for stripe.confirmCardPayment intent secret: value should be a client_secret string
My front-end functions:
const createSubscription = async () => {
setProcessing(true);
setWait('PLEASE WAIT');
try {
// create a payment method
const paymentMethod = await stripe?.createPaymentMethod({
type: "card",
card: elements?.getElement(CardElement),
billing_details: {
name,
email,
},
});
// call the backend to create subscription
const response = await fetch("https://XXX.cloudfunctions.net/tplannersubscription", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
paymentMethod: paymentMethod?.paymentMethod?.id,
name,
lname,
email,
priceId
}),
}).then((res) => res.json());
const confirmPayment = await stripe?.confirmCardPayment(
response.clientSecret
);
};
and my node function:
cors(request, response, async () => {
// create a stripe customer
try {
if (request.method != "POST") return response.status(400);
const { name, email, paymentMethod } = request.body;
// Create a customer
const customer = await stripe.customers.create({
email,
name,
payment_method: paymentMethod,
invoice_settings: { default_payment_method: paymentMethod },
});
// const priceId = request.priceId;
// Create a subscription
const subscription = await stripe.subscriptions.create({
customer: customer.id,
items: [{ price: "price_1KZ3nTGxUje7SlyIDUfIXkr3" }],
payment_settings: {
payment_method_options: {
card: {
request_three_d_secure: "any",
},
},
payment_method_types: ["card"],
save_default_payment_method: "on_subscription",
},
payment_behavior: "default_incomplete",
trial_period_days: 7,
expand: ["latest_invoice.payment_intent"],
});
// Send back the client secret for payment
response.json({
message: "Subscription successfully initiated",
clientSecret: subscription.latest_invoice.payment_intent.client_secret,
subID:subscription.id
});
} catch (err) {
console.error(err);
response.status(500).json({ message: "Internal server error" });
}
});
If I take out the Trial_period_days then it works fine, but if I include it it returns the error as mentioned above.
