小程序云函数调用出现的问题，如何解决？
调用代码如 下：add.js wx.cloud.init() Page({ /** * 页面的初始数据 */ data: { }, addData:function(event){ wx.cloud.callFunction({ name: 'addData' }).then(res => { console.log(res) }) } }) 出现的报错如下： VM42 WAService.js:1 Uncaught (in promise) Error: errCode: -404011 cloud function execution error | errMsg: cloud.callFunction:fail requestID , cloud function service error code -501000, error message Environment not found; at cloud.callFunction api; at new u (VM42 WAService.js:1) at d (VM42 WAService.js:1) at f (VM42 WAService.js:1) at Function.success (VM42 WAService.js:1) at VM42 WAService.js:1 at C (VM42 WAService.js:1) at i.<anonymous> (VM42 WAService.js:1) at i.emit (VM42 WAService.js:1) at Yi (VM42 WAService.js:1) at VM42 WAService.js:1 云函数文件：index.js // 云函数入口文件 const cloud = require('wx-server-sdk') cloud.init() const db = wx.cloud.database() const productsCollection = db.collection('products') // 云函数入口函数 exports.main = async (event, context) => { return await productsCollection.add({ data:{ titile: "product 1", image: 'https://res.wx.qq.com/wxdoc/dist/assets/img/0.4cb08bb4.jpg', tags: ["tga1", "tag2"], price: 120.12, color: 'red' } }) }
