两个云函数有一个调用成功，另一个报错，下面为调用失败的云函数。

// 云函数入口文件
const cloud = require('wx-server-sdk')
cloud.init()

// 云函数入口函数
const db = cloud.database()
const MAX_LIMIT = 100
exports.main = async (event, context) => {
  const new_name = event.a
  // 先取出集合记录总数
  const countResult = await db.collection(new_name).count()
  const total = countResult.total
  // 计算需分几次取
  const batchTimes = Math.ceil(total / 100)
  // 承载所有读操作的 promise 的数组
  const tasks = []
  for (let i = 0; i < batchTimes; i++) {
    const promise = db.collection(new_name).skip(i * MAX_LIMIT).limit(MAX_LIMIT).get()
    tasks.push(promise)
  }
  // 等待所有
  return (await Promise.all(tasks)).reduce((acc, cur) => {
    return {
      data: acc.data.concat(cur.data),
      errMsg: acc.errMsg,
    }
  })
}

wx.cloud.callFunction({
      name:'tichu',
      data: {
        a: 'allplayers'
      },
      success: res => {
          console.log(res)
      },
      fail :err => {console.log(err)}
  });

本地调试的错误为：

[error] 函数执行失败（耗时 107ms） Error: collection.count:fail -501003 exceed request limit. [ResourceUnavailable.ResourceOverdue] Resource has expired. Please renewal fee, but if the problem cannot be solved, contact us.
