firebase实时数据库触发器中的promise链接问题

exports.myTrigger = functions.database.ref('/path/to/data').onWrite(async (change, context) => {
  try {
    // 读取数据
    const data = await change.after.val();
    
    // 执行异步操作1
    const result1 = await asyncOperation1(data);
    
    // 执行异步操作2
    const result2 = await asyncOperation2(result1);
    
    // 执行异步操作3
    const result3 = await asyncOperation3(result2);
    
    // 写入数据
    await change.after.ref.child('result').set(result3);
    
    console.log('操作完成');
  } catch (error) {
    console.error('操作失败', error);
  }
});

// 异步操作1
function asyncOperation1(data) {
  return new Promise((resolve, reject) => {
    // 执行异步操作...
    // 完成后调用resolve或reject
  });
}

// 异步操作2
function asyncOperation2(data) {
  return new Promise((resolve, reject) => {
    // 执行异步操作...
    // 完成后调用resolve或reject
  });
}

// 异步操作3
function asyncOperation3(data) {
  return new Promise((resolve, reject) => {
    // 执行异步操作...
    // 完成后调用resolve或reject
  });
}
