Google Cloud Functions错误:“无法从Firestore值解码类型" [英] Google Cloud Functions Error: "Cannot decode type from Firestore Value"

问题描述

在React应用中使用Firestore，Im使用Google Cloud Functions进行测试以获取文档字段，然后使用该字段在Firestore中创建一个新字段.前几天我让它工作了，但现在却没有.

Using Firestore in a React app, Im testing out using Google Cloud Functions to grab a document field, and then create a new field in Firestore using that field. I had it working the other day and now it is not.

这是我在Google Cloud Function日志中得到的错误:

This is the error that Im getting in the Google Cloud Function log:

错误:无法从Firestore值中解码类型:{"stringValue":"sox"} 在DocumentSnapshot._decodeValue

Error: Cannot decode type from Firestore Value: {"stringValue":"sox"} at DocumentSnapshot._decodeValue

下面是我使用的代码.它与此处的代码非常相似: https://firebase.google .com/docs/firestore/extend-with-functions#writing_data

Below is the code I used. It is very similar to the code here: https://firebase.google.com/docs/firestore/extend-with-functions#writing_data

exports.createShowDoubleName = functions.firestore
  .document('shows/{showId}')
  .onUpdate((event) => {
    const data = event.data.data();
    const previousData = event.data.previous.data();
    if (data.name == previousData.name) return;
    var name = data.name;
    var newname = name+"_"+name
     return event.data.ref.set({
        newname: newname
      }, {merge: true});
});

推荐答案

firebase-functions SDK

firebase-functions SDK version 0.7.5 is supposed to fix the problem. It now forces a peer dependency on firebase-admin 5.5.0. Get it:

npm install firebase-functions@0.7.5
