Stripe订阅计划事件异常：仅单用户触发支付相关事件

我正在开发互助基金（chit fund）系统，使用Stripe Subscription Schedule为用户创建订阅，已保存支付详情实现自动扣费。批量为3-4名用户创建按日启动的4天期订阅计划，所有订阅均成功创建，但仅一名用户的invoice.payment_succeeded或invoice.payment_failed事件出现在Stripe开发者后台事件日志中，其他用户无相关日志。

已配置Webhook端点监听subscription_schedule.completed等事件，但未触发该类事件。期望通过subscription_schedule相关事件更新数据库订阅状态，却无法获取所有用户的订阅成功事件响应。以下是相关代码：

// 创建SetupIntent
const setupIntent = await stripe.setupIntents.create({
  customer: user.customerId,
  usage: "off_session",
  automatic_payment_methods: {
    allow_redirects: "never",
    enabled: true,
  },
});

// 设置默认支付方式
const paymentMethods = await stripe.customers.update(customerId, {
  invoice_settings: {
    default_payment_method: paymentMethodId,
  },
});

// 创建订阅计划
const subscription = await stripe.subscriptionSchedules.create({
  customer: customerId,
  start_date: unixTimestampSeconds,
  end_behavior: "release",
  phases: [
    {
      items: [
        {
          price: priceId,
          quantity: quantity,
        },
      ],
      iterations: iteration,
    },
  ],
});

// 保存订阅到数据库
const subs = await Subscription.create({
  subscriptionId: subscription?.id,
  userId: userId,
  programId: programId,
  status: subscription.status,
  startDate: start_date,
  endDate: end_date,
});

// Stripe Webhook处理逻辑
case "subscription_schedule.released":
  const subscriptionScheduleReleased = event.data.object;
  
  let user = User.findOne({
    where: { customerId: subscriptionScheduleReleased.customer },
  });
  const subscriptionSchedule = await stripe.subscriptionSchedules.retrieve(
    subscriptionScheduleReleased.id
  );
  let newsubscription =
    subscriptionSchedule.subscription ||
    subscriptionSchedule.released_subscription;
  const subscription = await stripe.subscriptions.retrieve(newsubscription);
  const datasubscription = await Subscription.findOne({
    where: { subscriptionId: subscriptionScheduleReleased.id },
  });
  datasubscription.status = subscription.status;
  console.log(subscriptionScheduleReleased, "subscription released");
  // 此处需定义并调用处理subscription_schedule.released事件的函数
break;

已监听的Stripe事件包括：

• subscription_schedule.aborted
• subscription_schedule.canceled
• subscription_schedule.completed
• subscription_schedule.created
• subscription_schedule.expiring
• subscription_schedule.released
• subscription_schedule.updated
