Can't Get Firebase Google App Script Quickstart Tutorial to Work

Question

I can't seem to get the Firebase QuickStart to work for me. I'm pretty sure that I followed all of the instructions correctly. But I'm not getting access to write to the database. And according to the instructions the database is currently open to the public with the suggest rules change displayed below. Has anybody ever gone through this tutorial before? I'd like a hint as to what to do next.

Here's the code.

  function writeDataToFirebase() {
  var ss = SpreadsheetApp.openById("1rV2_S2q5rcakOuHs2E1iLeKR2floRIozSytAt2iRXo8");
  //var ss = SpreadsheetApp.getActive();//I tried running it with data in this spreadsheet copied from the recommended source
  var sheet = ss.getSheets()[0];
  //var sheet = ss.getActiveSheet();
  var data = sheet.getDataRange().getValues();
  var dataToImport = {};
  for(var i = 1; i < data.length; i++) {
    var firstName = data[i][0];
    var lastName = data[i][1];
    dataToImport[firstName + '-' + lastName] = {
      firstName:firstName,
      lastName:lastName,
      emailAddress:data[i][2],
      country:data[i][4],
      department:data[i][5],
      weight:data[i][6],
      birthDate:data[i][7]
    };
  }
  var firebaseUrl = "https://script-examples.firebaseio.com/";
  var base = FirebaseApp.getDatabaseByUrl(firebaseUrl);
  base.setData("", dataToImport);
}

So I guess I missed an important point. The url of firebase database has your projectId in it. So the url would be something like https://' + projectId + '.firebaseio.com' . Sorry, to bother everyone with such a simple question.
