Authentication problem with firebase 3.0 on node.js

Because firebase has upgraded to version 3.0 and needs to be migrated to the new version, a problem has arisen regarding the authentication of my server node. The code is like this

var firebase = require('firebase');

var config = {
  apiKey: "<minha apiKey>",
  authDomain: "<meu domínio de autenticação>",
  databaseURL: "<url do banco>",
  storageBucket: "<minha storageBucket>",
  serviceAccount: "<nome do arquivo gerado pela conta de serviço>.json"
};

firebase.initializeApp(config);

When running npm start, the following error appears:

FIREBASE WARNING: Provided authentication credentials are invalid. 
This   usually indicates your FirebaseApp instance was not initialized correctly. 
Make sure your apiKey and databaseURL match the values provided for your 
app at 'https://console.firebase.google.com/', or if you're using 
a service account, make sure it's authorized to access the specified 
databaseURL and is from the correct project.

Being that I got all the config information in my own project console on the firebase.
