I’m integrating Stripe with my SaaS and I’m calculating the quota using the valid payment period, but Stripe always returns the period as being from the 70s, even though I have defined the plan as monthly, it comes with the beginning through the webhook and end on the same day in the 70s

// webhook

import Stripe from "stripe";
import { headers } from "next/headers";

import {
  processWebhookInvoiceSuccess,
  processWebhookSubscription,
  stripe,
} from "@/services/stripe";

export async function POST(req: Request) {
  const body = await req.text();
  const signature = headers().get("Stripe-Signature") as string;

  let event: Stripe.Event;

  try {
    event = stripe.webhooks.constructEvent(
      body,
      signature,
      process.env.STRIPE_WEBHOOK_SECRET
    );
  } catch (error: any) {
    console.error(`Webhook Error: ${error.message}`);
    return new Response(`Webhook Error: ${error.message}`, { status: 400 });
  }

  switch (event.type) {
    case "customer.subscription.created":
    case "customer.subscription.updated":
      await processWebhookSubscription(event.data.object);
      break;
    case "invoice.payment_succeeded":
      await processWebhookInvoiceSuccess(event.data.object);
    default:
      console.log(`Unhandled event type ${event.type}`);
  }

  return Response.json({ ok: true }, { status: 200 });
}
