Firebase函数onCall，响应：警告，缺少FIREBASE_CONFIG环境变量。初始化firebase-admin将失败

Question

我尝试从本地项目调用测试函数。

但是，每次我打电话时，我都遇到401错误。我不知道这有什么麻烦，在前端，我有带有api键的初始化应用程序，在Firebase函数中，我有admin.credential.applicationDefault()； 我试图通过admin.credential.cer(apiConfig)，但这无济于事。

我还有环境变量GOOGLE_APPLICATION_CREDENTIALS，其中包含我的配置路径。

依赖项

    "firebase-admin": "~7.0.0",
    "firebase-functions": "^2.2.0",
    "firebase-functions-test": "^0.1.6",

我的功能

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';

admin.initializeApp({
    credential: admin.credential.applicationDefault(),
    databaseURL: "https://plan-list.firebaseio.com"
});

exports.createInviteUser = functions.https.onCall( (data, context)=> {

  return data;

});

前端功能请求

 createInviteUser(email: string) {
        let inviteFunction = firebase.functions().httpsCallable('createInviteUser');

        inviteFunction(email)
            .then((result) => {
            // Read result of the Cloud Function.
           console.log(result);
        })
            .catch(err=>{
                console.log(err)
            });
    }

另外，我怎么看我拥有所有必需的标题

在Node v10中部署功能时会发生此错误。它是由bug in firebase-functions引起的。有一个修复程序，但尚未发布。在此之前，通过更改package.json文件将其降级到Node v8：

  "engines": {
    "node": "8"
  }
