Create the params hash if it doesn't exist.

???

albums_controller.rb 
class AlbumsController < ApplicationController

  def index
    params.new(:status) if params[:status].nil?
  end

end

The second part of the same challenge:

Challenge Task 2 of 2

Assign the @activities variable to a call of Activity.for_user(current_user) and send in the params.

class AlbumsController < ApplicationController

  def index
    # Write your code here.
    params[:page] ||= 1
    @activities = Activity.for_user(current_user, params)
  end

end

I found the needed second line of code on this Github page:

Around 3:36 you will get a hint. Something like params[:page] ||= 1
