Code challenge troubles: Finding and Building Models 2/3

I'm having troubles passing this code challenge. I've managed to pass the first stage, but then I got stuck in the 2nd stage, and I can't figure out why.

The task is to "Find the friend specified by the friend_id param and set it to a friend instance variable." My solution was to add this code, which was also used (if I'm not mistaken) in the prior video:

@friend = User.find(params[:friend_id])

I tried to add it as an additional line of code just below the one I wrote to (successfully) pass the 1st stage. I failed (more like errored out - some sort of a message about the code challenges engine crashing - but when refreshed I managed to pass 1st stage again). Then I tried it with the if-else statement that was shown in the video, but also - nothing worked for me.

What am I doing wrong?

EDIT: Of course I passed a minute after posting this. How very Murphy. Anyway, TeamTreeHouse staff - something went bezerk lately in the code challenges module. I used to pass those in the past with no particular problems

I can't pass this challenge, this is my code:

class UserFriendshipsController < ApplicationController
  def new
    unless params[:friend_id].present?
      flash[:error] = 'Friend required'
    end
    @friend = User.find(params[:friend_id])
  end
end
