Попытка присвоить свойство только для чтения на Капибаре

Question

Я работаю над обновлением приложения rails 3.2 до rails 4.2.10, у меня почти все проработано, модульные и интеграционные тесты пройдены.

У меня возникли некоторые проблемы с тестами функцийЯ использую capybara 3.3.0 и poltergeist 1.18.1, и это вызывает ошибку на visit '/'

Я рассмотрел множество проблем со стеком, касающихся Попытка присвоить свойству только для чтения но ни один из них не применим к моему делу здесь,

Это мой урезанный файл спецификации

require 'vcr'

Capybara.default_max_wait_time = 10

feature "Create something"  do
  include SpecHelpers
  include Acceptance

  before do
    setup_database
  end

  after do
    teardown_database
  end

  scenario "Creating a Consignment", :js => true do

    puts "Running with #{Capybara.current_driver}"

    VCR.use_cassette('cassette_name.yml') do      
      page.driver.resize(1000,2200) unless Capybara.current_driver == :selenium
      visit '/'
      expect(page).to have_content 'EMAIL'
      expect(page).to have_content 'PASSWORD'


    end
  end

Обновление 1

При некоторой отладке получается, что ошибка генерируется из angularjs-bootstrap-datetimepicker пакет, когда он пытается установить $render на функцию,

var ngModelController = $element.controller('ngModel')

var configuration = createConfiguration()
$scope.screenReader = configuration.screenReader

// Behavior
$scope.changeView = changeView
ngModelController.$render = $render --> in this line
