错误:没有要更新的实体:app - Firestore Cloud Function [英] Error: no entity to update: app - Firestore Cloud Function

问题描述

这是我最基本的云功能:

const functions = require('firebase-functions');const admin = require('firebase-admin');admin.initializeApp(functions.config().firebase);const db = admin.firestore()export.createdNewAccount = functions.auth.user().onCreate(event => {返回 db.collection('users').doc(event.data.uid).update({"creationDate" : Date.now()})})

我得到了错误

<块引用>

错误:没有要更新的实体:app

我的代码有什么问题?

解决方案

很可能，event.data.uid 的文档不存在.update() 的文档指出:

<块引用>

如果应用于不存在的文档，更新将失败.

请改用 set().p>

This is my very basic Cloud Function:

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
const db = admin.firestore()

exports.createdNewAccount = functions.auth.user().onCreate(event => {
    return db.collection('users').doc(event.data.uid).update({
        "creationDate" : Date.now()
    })
})

And I get the error

Error: no entity to update: app

What is wrong with my code?

解决方案

Most likely, the document for event.data.uid does not exist. The documentation for update() states:

The update will fail if applied to a document that does not exist.

Use set() instead.
