Я написал следующий веб-хук для захвата событий, поступающих из stripe после того, как пользователь внес изменения в подписку:

 export const stripeWebhookEvents = functions.https.onRequest( async ( request: any, response: any ) => {
    // Retrieve the event by verifying the signature using the raw body and secret.
    let event;
    const signature = request.headers["stripe-signature"];
    try {
        event = stripe.webhooks.constructEvent(
            request.rawBody,
            signature,
            STRIPE_WEBHOOK
        );
    } catch (err) {
        console.log("⚠️  Webhook signature verification failed.", err);
        return response.sendStatus(400);
    }
    // Extract the object from the event.
    const eventType = event.type;
    console.log(`Scripe event type: ${eventType}.`);
    // Handle the event
    switch (eventType) {
        case "customer.subscription.created": {
            // Occurs whenever a customer is signed up for a new plan.
            console.log("customer.subscription.created");
            try {
                const session = event.data.object;
                console.log("stripe customer: ", session.customer);
                const userRecord = await getUserWithStripeCustomerID(session.customer);
                console.log("userRecord: ", userRecord);
                const data = {
                    "subscription_status": session.status,
                };
                await updateUser(userRecord, data);
            } catch (error) {
                console.log(error);
            }
            break;
        }
        case "customer.subscription.updated": {
            // Occurs whenever a subscription changes (e.g., switching from one plan to another,
            // or changing the status from trial to active).
            break;
        }
        case "customer.subscription.deleted": {
            // The subscription has been deleted so update the user document so that it shows
            // that the subscription is inactive.
        }
        case "invoice.payment_failed": {
            // The payment failed or the customer does not have a valid payment method.
            // The subscription becomes past_due. Notify your customer and send them to the
            // customer portal to update their payment information.
            // update the user document so that it shows that the subscription is inactive.
            break;
        }
        default: {
        // Unexpected event type
        console.log(`Unhandled event type ${eventType}.`);
        }
    }
    response.sendStatus(200);
});

Когда «клиент.подписка.создана», я хочу обновить идентификатор цены («price_1J3q2zHx6drz9dmy2bMdkXOs»), но я не уверен, как его получить. Я пытался:

 session.items.data[price.id]
 

но это не работает. Как мне получить доступ к идентификатору цены?
