- 当前 Bug 的表现（可附上截图）

- 预期表现

- 复现路径

- 提供一个最简复现 Demo

// 云函数入口文件

const cloud = require('wx-server-sdk')

cloud.init()

const db = cloud.database();

const MAX_LIMIT = 100

exports.main = async(event, context) => {

// 先取出集合记录总数

const wxContext = cloud.getWXContext()

const countResult = await db.collection('ORDER').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 = [];

const allOrder = [];

const waitOrder = [];

const finishOrder = [];

const cancelOrder = [];

const allOrderNum = total;

const watiOrderNum = 0;

const finishOrderNum = 0;

const cancelOrderNum = 0;

for (let i = 0; i < batchTimes; i++) {

const promise = db.collection('ORDER').where({

USER_OPEN_ID: wxContext.OPENID

}).skip(i * MAX_LIMIT).limit(MAX_LIMIT).get()

tasks.push(promise)

}

// 等待所有

return (await Promise.all(tasks)).reduce((acc, cur) => {

allOrder = acc.data.concat(cur.data)

console.log(allOrder)

for (let i = allOrder.length - 1; i >= 0; i--) {
