devise_async strange redis log

[rizalmuthi]

Hi,
I just setup my rails application using devise_async
This is my gem file looks like

gem 'sidekiq'
gem 'sinatra', require: false
gem 'devise'
gem 'devise-async'

and this is the setup on the config/initializers/devise_async.rb :

Devise::Async.setup do |config|
  config.enabled = true
  config.backend = :sidekiq
end

And setup for user.rb:

devise :database_authenticatable, :async, :confirmable

So I run my rails, redis-server, and sidekiq and also open the redis-cli
On the redis-cli i turn on the Monitor and i got this bunch of log, even I havent run anything like register the new user or sending email to confirm, etc from devise
