How to raise an error on duplicate column slug in FriendlyId?

I use friendly_id gem and if my slug column have duplicate value, gem updates it by adding a unique key. I want raise error already been taken. How can i do this?

It seems friendly_id(v5.2.4) does not have an option to avoid setting the UUID when a slug conflict happens. So the best way to solve this it to redefine the method responsible for resolving the conflict and raise an exception.

class Post < ApplicationRecord
  extend FriendlyId
  friendly_id :title, use: :slugged

  def resolve_friendly_id_conflict(candidates)
    raise ActiveRecord::RecordNotUnique
  end
end
