在小程序里选择视频上传，在云函数里面执行函数

const fs = require(‘fs’)

const path = require(‘path’)

cloud.init({

env: ‘wl-97aae6’

})

// 云函数入口函数

var timestamp = Date.parse(new Date());

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

const filename = “video/” + timestamp + event.videourl.match(/\.[^.]+?$/)[0]

const fileStream = fs.createReadStream(path.join(__dirname, event.videourl))

return await cloud.uploadFile({

cloudPath: filename,

fileContent: fileStream

})

}

总是报这个

这个该怎么做
