无法在 NodeJS 上的 Firebase 中读取未定义的属性（读取“getProvider”）

Question

我正在从 NodeJS 服务器开发 Firebase 云消息传递到我的 Android。

从 FCM 控制台页面接收通知成功。

我使用 FCM Docs 实现了服务器代码。 (https://firebase.google.com/docs/admin/setup)

但在运行时出现错误：

[0] TypeError: Cannot read properties of undefined (reading 'getProvider')

我的代码中没有“getProvider”。

我用谷歌搜索并尝试了替代代码

但它仍然无法正常工作。

这是我的代码。

...
// const { initializeApp } = require('firebase-admin/app');
// const fbapp = initializeApp();

//const { getMessaging } = require("firebase/messaging");
const { getMessaging } = require("firebase/messaging/sw");

const admin = require("firebase-admin");
const serviceAccount = require('../../server/firebase-adminsdk-asdf.json');
const fbapp = admin.initializeApp({
    credential: admin.credential.cert(serviceAccount)
});

const registrationTokens = [
    'ePBbqfWEQ7yaj5Zjxera98...',
    // …
];

const message = {
    notification: { title: req_body.writer, body: req_body.title },
    tokens: registrationTokens,
};

getMessaging(fbapp)
    // .sendMulticast(message)
    .sendAll([message])
    .then((response) => {
        console.log(response.successCount + ' messages were sent successfully');
    });

Answer 1

不是 firebase 专家，但似乎 sendAll 消息需要一个没有 s 的 token 属性，而 sendMulticast 接受 tokens。 阅读文档后，这实际上是有道理的：

• token 将每条消息发送到 1 个目标
• tokens 将每条消息发送到 n 个目标

您好，我遇到了与此类似的问题。你找到解决这个问题的办法了吗？
