Firebase 功能模拟失败

Question

我正在使用 typescript/firebase/firestore 设置 NextJS 应用程序，并模拟函数、firestore 和身份验证以进行开发。我有一个 firebase 函数，可以在创建用户时随时运行。

firebase/functions/index.ts

：

import { firestore } from "firebase-admin";
import { initializeApp } from "firebase-admin/app";
import { getAuth } from "firebase-admin/auth";
import { auth, config } from "firebase-functions";

initializeApp(config().firebase);

export const onUserCreate = auth.user().onCreate(async (user) => {
    if (user.email && user.email === "[email protected]") {
        await firestore().doc(`users/${user.uid}`).create({
            isCoordinator: true,
        });

        const customClaims = {
            role: "coordinator",
        };

        try {
            await getAuth().setCustomUserClaims(user.uid, customClaims);
        } catch (error) {
            console.log(error);
        }
        return;
    }

    if (user.email && user.email === "[email protected]") {
        const customClaims = {
            role: "recruiter",
        };

        try {
            await getAuth().setCustomUserClaims(user.uid, customClaims);
        } catch (error) {
            console.log(error);
        }
        return;
    }

    await firestore().doc(`users/${user.uid}`).create({
        isRecruiter: false,
    });
});

firebase/functions/package.json

{
  "name": "functions",
  "scripts": {
    "lint": "eslint --ext .js,.ts .",
    "build": "tsc",
    "build:watch": "tsc --watch",
    "serve": "npm run build && firebase emulators:start --only functions",
    "shell": "npm run build && firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "engines": {
    "node": "20"
  },
  "main": "lib/index.js",
  "dependencies": {
    "firebase-admin": "^12.0.0",
    "firebase-functions": "^4.6.0"
  },
  "devDependencies": {
    "@typescript-eslint/eslint-plugin": "^5.12.0",
    "@typescript-eslint/parser": "^5.12.0",
    "eslint": "^8.9.0",
    "eslint-config-google": "^0.14.0",
    "eslint-plugin-import": "^2.25.4",
    "firebase-functions-test": "^3.1.0",
    "typescript": "^4.9.0"
  },
  "private": true
}

但是，运行时

firebase emulators:start

我收到以下错误：

!!  functions: Failed to load function definition from source: FirebaseError: User code failed to load. Cannot determine backend specification

类似的问题已经在他们的 GitHub 上的 this issues 下进行了讨论，但没有任何实际结果。我已经降级了（正如许多人在问题讨论中建议的那样），但这没有任何帮助。

特别奇怪的是，它偶尔会起作用，我可以成功地使用云功能来做我想做的事情。有人知道我能做些什么来解决这个问题吗？

尝试贬值它，它对我有用 npm install firebase-functions@^4.4.0 firebase-admin@^11.10.0
