谷歌云功能错误 DEADLINE EXCEEDED

Question

我正在尝试编写一个简单的发布/订阅触发的云函数来更新我的 Firestore 股票集合。我收到了一堆奇怪的错误消息，其中一个突出显示错误：4 DEADLINE_EXCEEDED：超过截止日期。更奇怪的是，有些股票可以正确更新，而有些则不能。我是 Javascript/Typescript 的新手，所以很明显我对如何在这种情况下返回承诺有一些误解。这里的想法是非常简单的循环遍历集合中的每个股票行情，请求更新数据，然后更新现有文档数据并保存

export const updateChart = functions.pubsub.schedule('35 16 * * 1-5').timeZone('America/New_York').onRun(async(_context) => {
const key = functions.config().services.key as string 
const db = admin.firestore()
const charts5DRef = db.collection("charts5D")
var needsUpdate : boolean = true 
// I cut off some unrelated code for brevity sake 
if (needsUpdate){
    const snapshot = await charts5DRef.get()
    var path = ``
    const timestamp = Date.now() / 1000
    return snapshot.forEach(async function(document){ // this  could contain 100's of stock tickers
        const ticker = document.id
        const docData = document.data()
        var labels = docData.labels as [string]
        var marketNotional = docData.marketNotional as [number]
        var marketTrades = docData.marketNumberOfTrades as [number]
        var dates = docData.dates as [string]
        var closings = docData.close as [number]
        var volume = docData.marketVolume as [number]

        const options = {

        }
        await req(options).then(async(response)=>{
            if(response.statusCode === 200){
                const resultData = JSON.parse(response.body)
                const updatedPrices = resultData as [IntradayPrice]
                updatedPrices.forEach(function(value){
                    if(value.close !== undefined){
                        closings.splice(0,1)

                        closings.push(value.close)
                        dates.push(value.date)
                        if(value.label !== undefined){ labels.push(value.label) } else { labels.push("") }
                        if(value.marketNotional !== undefined) { marketNotional.push(value.marketNotional) } else { marketNotional.push(0) }
                        if(value.marketNumberOfTrades !== undefined) { marketTrades.push(value.marketNumberOfTrades) } else { marketTrades.push(0) }
                        if(value.marketVolume !== undefined) { volume.push(value.marketVolume) } else { volume.push(0) }
                    }

                    console.log(`Updated ${ticker} 5Dchart successfully`)
                }).catch((error)=>{

        })
    })

好的，这样就解决了错误
