cloud.downloadFile 云函数生产环境调用无反应？
现象：本地环境调试，可以获取图片资源的buffer。上传到正式环境，获取不到数据，且无异常信息。云函数设置超时时间都是20s；
相关代码：
// 传入一个小程序云存储的path，返回图片对应的资源id
const getImgMediaId = async function (imgPath) {
// 下载图片
const fileID = `${cloudFilePrefix}${imgPath}`
let finalRes = {}
let downFileRes = {}
console.log("fileID", fileID)
try {
downFileRes = await cloud.downloadFile({
fileID: fileID
})
console.log("downFileRes", downFileRes)
} catch (e) {
console.log(111, e)
}
try {
// 上传图片
finalRes = await cloud.openapi.customerServiceMessage.uploadTempMedia({
type: 'image',
media: {
contentType: 'image/jpeg',
value: file
}
})
} catch (e) {
console.log(222, e)
}
return finalRes
}
