错误:4 DEADLINE_EXCEEDED:在 Object.exports.createStatusError 处超出截止日期 - GCP [英] Error: 4 DEADLINE_EXCEEDED: Deadline Exceeded at Object.exports.createStatusError - GCP

问题描述

我正在尝试从我的 Google Cloud Functions 之一创建 Google Cloud 任务.当一个新对象添加到我的一个 Cloud Storage 存储分区时，会触发此函数.

I am trying to create a google cloud task from one of my Google Cloud Functions. This function gets triggered when a new object is added to one of my Cloud Storage buckets.

我按照此处给出的说明创建了我的 App Engine(App Engine 快速入门指南)

I followed the instructions given here to create my App Engine (App Engine Quickstart Guide)

然后在我的云函数中，我添加了以下代码来创建云任务(如此处所述 - 创建 App Engine 任务)

Then in my Cloud Function, I added the following code to create a cloud task (as described here - Creating App Engine Tasks)

但是，我的任务或 App Engine 调用有问题(不确定是什么).

However, there is something wrong with my task or App Engine call (not sure what).

我不时收到以下错误.有时有效，有时无效.

I am getting the following errors every now and then. Sometimes it works and sometimes it does not.

{ Error: 4 DEADLINE_EXCEEDED: Deadline Exceeded at Object.exports.createStatusError (/srv/node_modules/grpc/src/common.js:91:15) at Object.onReceiveStatus (/srv/node_modules/grpc/src/client_interceptors.js:1204:28) at InterceptingListener._callNext (/srv/node_modules/grpc/src/client_interceptors.js:568:42) at InterceptingListener.onReceiveStatus (/srv/node_modules/grpc/src/client_interceptors.js:618:8) at callback (/srv/node_modules/grpc/src/client_interceptors.js:845:24) code: 4, metadata: Metadata { _internal_repr: {} }, details: 'Deadline Exceeded' }

如果您需要更多信息，请告诉我，我会将它们添加到此问题中.

Do let me know if you need more information and I will add them to this question here.

推荐答案

我在 firestore 上遇到了同样的问题，试图一次写一个文档；我通过返回总承诺来解决它.那是因为云函数需要知道什么时候方便终止函数，但是如果你不返回任何东西可能会导致这个错误.

I had the same problem with firestore, trying to write one doc at time; I solve it by returning the total promise. That is because cloud function needs to know when is convenient to terminate the function but if you do not return anything maybe cause this error.

我的例子:

data.forEach( d => {
       reports.doc(_date).collection('data').doc(`${d.Id}`).set(d);
    }) 

这就是我的问题，我正在逐一编写文档，但我没有返回承诺.所以我解决了这个问题:

This was the problem with me, I was writing document 1 by 1 but I wasn't returning the promise. So I solve it doing this:

const _datarwt = [];

data.forEach( d => {
          _datarwt.push( reports.doc(_date).collection('data').doc(`${d.Id}`).set(d) );
        }) 
const _dataloaded = await Promise.all( _datarwt );

我将返回的承诺保存在一个数组中并等待所有的承诺.那为我解决了.希望有所帮助.

I save the returned promise in an array and await for all the promises. That solved it for me. Hope been helpful.
