ruby Booleans Challenge 1 of 1

Why am I getting an error?

todo_list.rb 
class TodoList
  attr_reader :name, :todo_items

  def initialize(name)
    @name = name
    @todo_items = []
  end

  def add_item(name)
    todo_items.push(TodoItem.new(name))
  end

  def find_index(name)
    index = 0
    found = false
      todo_items.each do |todo_item|
          if todo_item == name
            found = true
     end
   end
    if found
       return index
    else
       return nil
   end
  end

To accomplish this challenge you need to move the if found check inside the method, compare todo_item.name against name, increment the index each time the item isn't found, and when it is found exit out of the loop (to keep the index from incrementing again):

  def find_index(name)
    index = 0
    found = false
    todo_items.each do |todo_item|
      if todo_item.name == name
          found = true
          break
        else
          index += 1  
        end
    end
    return found ? index : nil
   end
