Firebase 功能错误：默认 Firebase 应用不存在

Question

以前，该功能有效。但我添加了一些代码，现在这个错误来了。如何解决这个问题？

Error: Error occurred while parsing your function triggers.

Error: The default Firebase app does not exist. Make sure you call initializeApp() before using any of the Firebase services.
    at FirebaseAppError.FirebaseError [as constructor] (/Users/demo/functions/node_modules/firebase-admin/lib/utils/error.js:42:28)

代码

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
import { getLocations, getLocationsByType } from '../service/locationQuery/locationQuery';

//I tried both way, but same error came
// admin.initializeApp(functions.config().firebase);
admin.initializeApp();
exports.findUsers = functions.https.onCall(async (data: any, context: any) => {

我改变了初始化位置..现在它正在工作。我不知道为什么会这样。

import * as admin from 'firebase-admin';
admin.initializeApp();//add to here
import { getLocations, getLocationsByType } from '../service/locationQuery/locationQuery';

// admin.initializeApp(functions.config().firebase);

exports.findUsers = functions.https.onCall(async (data: any, context: any) => {
