如何在 firebase 中為 auth.user().onCreate() 觸發器創建日志記錄 function？

Question

每次創建和刪除帳戶時，我都試圖記錄。

我創建了一個觸發器functions.auth.user().onCreate() ，據我所知，它返回一個user object，如文檔中所示： here和 here 。

函數部署沒有問題，但是當調用觸發器時它會拋出錯誤：

Error: Process exited with code 16
at process.<anonymous> (/layers/google.nodejs.functions-framework/functions-framework/node_modules/@google-cloud/functions-framework/build/src/invoker.js:92:22)
at process.emit (events.js:314:20)
at process.EventEmitter.emit (domain.js:483:12)
at process.exit (internal/process/per_thread.js:168:15)

at processPromiseRejections (internal/process/promises.js:209:33)
at processTicksAndRejections (internal/process/task_queues.js:98:32) 

我無法理解的錯誤。

這是我的代碼

// functions/index.js    
const functions = require('firebase-functions')
const admin = require('firebase-admin')
const { google } = require('googleapis')
const { firestore } = require("firebase-admin");

exports.logging = require('./logging');

admin.initializeApp()
// And other working functions

實際功能

    // functions/logging.js

const functions = require('firebase-functions');
const admin = require('firebase-admin');
const { firestore } = require('firebase-admin');

const authUserTrigger = functions.auth.user()

exports.userSignup = authUserTrigger.onCreate((user) => {
  storeUser(user)
})

exports.userDelete = authUserTrigger.onDelete((user) => {
  storeUser(user)
})

    async function storeUser(user) {
      // functions.logger.log(user.email) -> this works

      // Destructured original object
      let updatedUser = (({ displayName, email }) => ({ displayName, email }))(user);
      functions.logger.log('updatedUser', updatedUser )
      await admin
        .firestore()
        .collection('logs')
        .doc('users')
        .collection('signup')
        .set({
          user: {updatedUser}, // I think this is the culprint
          // user,  This doesn't work either
          createTimestamp: firestore.FieldValue.serverTimestamp()
        }, { merge: true })
    
    };

先感謝您

編輯 ========== @Tanay 是對的。 需要更改set以add .

正如@Tanay 所述，您不能在 Firebase 的集合中使用set() ，它必須是文檔。 如果您想使用自動 ID 將文檔添加到集合中，則可以對包含數據的集合使用add() 。
