Help returning boolean values

def contains?(name) todo_items.include?(name) end

I'm getting an error message saying the contains? method is not returning a boolean value. I can't find my own error. Help is appreciated

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 contains?(name)
    return todo_items.include?(name)
  end

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

That is weird. I'm almost sure that I had similar code when doing this challenge a few weeks back and it worked. Other, more clumsy solutions don't work either.
