Firebase错误:“分析触发器时出错:找不到模块'./clone.js'”

当我跑的时候 firebase deploy --only functions 我收到以下错误消息:

Error parsing triggers: Cannot find module './clone.js'

这是我的代码,从 documentation :

const functions = require('firebase-functions');
const admin = require('firebase-admin');

const {Storage} = require('@google-cloud/storage');
const storage = new Storage();
const bucketName = 'myapp.appspot.com';
const filename = './hola_mundo.wav';

admin.initializeApp();

exports.Storage = functions.firestore.document('Test_Value').onUpdate((change, context) => {

  storage.bucket(bucketName).upload(filename, {
    gzip: true,
    metadata: {
      cacheControl: 'no-cache'
    }
  })
  .then(() => {
    console.log(`${filename} uploaded to ${bucketname}`);
  })
  .catch(err => {
    console.error(err);
  });

});

是 clone.js npm module ?
