no implicit conversion from nil to integer (TypeError)

[Chuck Shriver]

Hello,

I am getting a
  no implicit conversion from nil to integer (TypeError) 

Are there any changes I can make to fix it? Source code and run results are below. 

Thanks!!

require_relative '../features/support/pages/side_menu_panel'

class HomePage
  include PageObject
  include SideMenuPanel
  page_url "http://puppies.herokuapp.com"

  buttons(:view_detail, :value => 'View Details')

  def select_puppy(name = 'Brook')
    index = index_for(name)
    view_detail_elements[index].click
  end

  private

  def index_for(name)
    name_elements.find_index { |the_div| the_div.text == name }

Try debugging theses two lines

index = index_for(name)

view_detail_elements[index].click

Looks like index is nil, meaning it can't find the index for the name you're passing in resulting in a nil index.  Nil cannot be converted into an integer ( that's the error you're getting )

Thanks, this has been resolved. A key part of the resolution involved restoring
