如何等待两个OnCreate Firebase函数完成

// 第一个OnCreate函数
exports.onCreateFunction1 = functions.firestore.document('collection/{docId}').onCreate((snapshot, context) => {
  const promise = new Promise((resolve, reject) => {
    // 执行函数的逻辑
    // ...
    resolve();
  });

  return promise;
});

// 第二个OnCreate函数
exports.onCreateFunction2 = functions.firestore.document('anotherCollection/{docId}').onCreate((snapshot, context) => {
  const promise = new Promise((resolve, reject) => {
    // 执行函数的逻辑
    // ...
    resolve();
  });

  return promise;
});

// 主函数
exports.waitOnCreateFunctions = functions.https.onRequest((req, res) => {
  Promise.all([
    exports.onCreateFunction1(snapshot, context),
    exports.onCreateFunction2(snapshot, context)
  ]).then(() => {
    res.send('两个OnCreate函数已完成');
  }).catch((error) => {
    res.status(500).send('等待两个OnCreate函数出错：' + error);
  });
});

// 第一个OnCreate函数
exports.onCreateFunction1 = functions.firestore.document('collection/{docId}').onCreate(async (snapshot, context) => {
  // 执行函数的逻辑
  // ...
});

// 第二个OnCreate函数
exports.onCreateFunction2 = functions.firestore.document('anotherCollection/{docId}').onCreate(async (snapshot, context) => {
  // 执行函数的逻辑
  // ...
});

// 主函数
exports.waitOnCreateFunctions = functions.https.onRequest(async (req, res) => {
  try {
    await exports.onCreateFunction1(snapshot, context);
    await exports.onCreateFunction2(snapshot, context);
    res.send('两个OnCreate函数已完成');
  } catch (error) {
    res.status(500).send('等待两个OnCreate函数出错：' + error);
  }
});
