What could be the problem, tasks are not visible in resque-history?

Question

ruby

What could be the problem? I use the resque-history plugin to monitor completed/failed tasks.
Everything is simple in the documentation - add to routes After these manipulations, the history tab appears in the resque dashboard. Here is the code in the taskrequire 'resque-history/server'

require 'resque-history'

class WelcomeEmailJob < ActiveJob::Base
  extend Resque::Plugins::History
  @max_history = 200
  @queue = :email

  def perform(user)
    UserMailer.welcome_email(user).deliver_now
    puts "I delivered mail to #{user.login} now, sincerly yours Resque <3"
  end
end

The statistics show that the tasks were completed, everything worked out, but the history is not shown
