测试Firebase httpsCallable函数时客户端报FirebaseError: internal错误求助

复现步骤 #

1. 执行firebase init初始化Firebase配置，选择Functions和Emulators。
2. 在模拟器选项中选择Functions模拟器和UI模拟器，分别为Functions模拟器分配端口5001，UI模拟器分配端口2000。
3. 为Functions选择TypeScript，等待依赖下载完成后，将以下代码粘贴到functions/src/index.ts中：

import * as functions from "firebase-functions";

export const helloWorld = functions.https.onCall((data, context) => {
    console.log(data);
    return { success : true };
});

4. 进入functions/目录执行npm run build构建函数，然后执行firebase emulators: start启动Firebase模拟器。
5. 新建项目，安装Firebase SDK并通过firebaseConfig初始化SDK，代码如下（src/index.ts）：

import { initializeApp } from "firebase/app";
import { connectFunctionsEmulator, getFunctions, httpsCallable } from "firebase/functions";

const firebaseConfig = { /*...firebaseConfig*/ };

const app = initializeApp(firebaseConfig);
const functions = getFunctions(app);
const useEmulator:boolean = true

if(useEmulator) {
    connectFunctionsEmulator(functions, "localhost", 5001);
}

const triggerCallable = httpsCallable(functions, "helloWorld");
const result = await triggerCallable({
    message : "Hello world",
    count: 1
});
console.log(result); // expected : { success : true }

6. 执行npm run build && node dist/index.js运行编译后的文件，出现以下错误：

node:internal/process/esm_loader:97
    internalBinding('errors').triggerUncaughtException(
                              ^

[FirebaseError: internal] {
  code: 'functions/internal',
  customData: undefined,
  details: undefined
}

模拟器日志中看不到函数初始化的信息，但能看到✔ functions: Loaded functions definitions from source: helloWorld.这条日志。

尝试使用第二代Firebase函数的onCall()，同样出现FirebaseError: internal错误，看起来函数并未正确初始化。
