Question

有人可以协助解决此错误吗？我已经看到了类似的答案：“ Firebase Firestore云功能显示错误：无效地使用类型“ undefined”作为Firestore参数”，但是该答案无济于事。

Error: Invalid use of type "function" as a Firestore argument.

该功能在ionic 4应用程序中使用：

import * as functions from "firebase-functions";
import * as admin from "firebase-admin";
admin.initializeApp();

const db = admin.firestore();

export const userSignupData = functions.auth.user().onCreate((user, context) => {
  const userRef = db.doc(`users/${user.uid}`);

  return userRef.set({
    id: user.uid,
    createdAt: context.timestamp,
    signupEmail: user.email,
    emailVerified: user.email,
    originalSigninProvider: user.providerData
  });
});

Answer 1

firebase似乎不喜欢set对象中的重复属性调用。

signupEmail: user.email,
emailVerified: user.email,

Answer 2

在您要上传的数据中，context.timestamp可能是函数类型，这意味着您试图将函数而不是有效的“日期”或“时间戳”推送到firestore。

根据this thread on creating timestamps in firestore，您可以传递截至 2019年2月的有效时间戳，例如：

firestore().collection("item")
.add({...item, created: firebase.firestore.Timestamp.fromDate(new Date()) })

Firestore云函数错误：无效地将类型“ function”用作Firestore参数。
