аюсь развернуть функцию в Firebase

$ npm install firebase-tools
$ login firebase
$ firebase init functions

тогда$firebase deploy --only functions или же$firebase deploy

package.json:

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "lint": "eslint .",
    "serve": "firebase serve --only functions",
    "shell": "firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "dependencies": {
    "firebase-admin": "~5.12.1",
    "firebase-functions": "^1.0.3"
  },
  "devDependencies": {
    "eslint": "^4.12.0",
    "eslint-plugin-promise": "^3.6.0"
  },
  "private": true
}

firebase.json:

{
  "functions": {
    "predeploy": [
      "npm --prefix \"%RESOURCE_DIR%\" run lint"
    ]
  }
}

отредактировано с$RESOURCE_DIR как%RESOURCE_DIR% избежать:

Ошибка: ошибка предустановки функций: команда завершена с ненулевым кодом выхода4294963238

моя функцияindex.js:

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

admin.initializeApp(functions.config().firebase);
var wrotedata;
exports.Pushtrigger = functions.database.ref('/messages/{messageId}').onWrite((event) => {
    wrotedata = event.data.val();

    admin.database().ref('/pushtokens').orderByChild('uid').once('value').then((alltokens) => {
        var rawtokens = alltokens.val();
        var tokens = [];
        this.processtokens(rawtokens).then((processedtokens) => {

            for (var token in processedtokens) {
                tokens.push(token.devtoken);
            }

            var payload = {
                "notification": {
                    "title": "Notification title",
                    "body": "Notification body",
                    "sound": "default",
                    "click_action": "FCM_PLUGIN_ACTIVITY",
                    "icon": "fcm_push_icon"
                },
                "data": {
                    "message": "value1",
                    "sendername": "value2"
                }
            }
                return admin.messaging().sendToDevice(tokens, payload).then((response) => {
                    console.log('Push notifications');
                }).catch((err) => {
                    console.log(err);
                })             
        })
    })
})

function processtokens(rawtokens) {
    var promise = new Promise((resolve, reject) => {
        var processedtokens = []
        for (token in rawtokens) {
            processedtokens.push(rawtokens[token]);
        }
        resolve(processdatatokens);
    })
    return promise;
}

Я пробовал:

npm install firebase-admin@latest firebase-functions@latest
npm install -g git://github.com/firebase/firebase-tools#master

но я получил:

похоже, что-то не так с кодом, потому что развертывание по умолчаниюHello from Firebase! успешно

редактировать:
