I am trying to use the queuing module base on top of Firebase. I use the following code to push tasks

import admin from "firebase-admin";


admin.initializeApp({
  credential: admin.credential.cert(process.env.GOOGLE_APPLICATION_CREDENTIALS),
  databaseURL: 'gs://xxx.appspot.com/'
});


var db = admin.database();
var ref = db.ref("queue");

ref.child('tasks').push({"name": "this is a push from the client"}).then(function(){ process.exit();});

But nothing is happening. The task is not pushed and the pushing task does not exit or throw any error
