用firebase cloud function寫api
我用的是typescript
我部署從別的ts匯入的function
結果發生找不到的error
是我export寫錯嗎？

檔案結構:
functions
|-lib
|-node_modules
|-src
|-index.ts
|-common.ts

index.ts

import * as functions from 'firebase-functions';
const admin = require('firebase-admin');
const firebase = require('firebase');

admin.initializeApp();

const firebaseConfig = {
};

firebase.initializeApp(firebaseConfig);

import * as _common from './common';

module.exports = {
  _common
};

common.ts

export const log = functions.https.onCall(async (data: any, context: any) => {
    
    // process
    
});

cmd: firebase deploy --only functions:log

error: the following filters were specified but do not match any functions in the project: log
