devise-async not executing enqueue jobs with sidekiq

Question

I was working with devise and devise-async and it was sending emails with sidekiq using devise-async. But recently it stops to work and I am not able to find the issue.

Gems I'm using

    gem 'devise'
    gem 'devise-async'

config/initilizer/devise-async.rb

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

passwords_controller.rb

  def create
   #Here im sending emails with the below command
   self.resource =resource_class.send_reset_password_instructions(resource_params)
    yield resource if block_given?
  end

user.rb

  devise :database_authenticatable,:async,
         :recoverable, :rememberable, :validatable,
         :lockable, :timeoutable, :trackable

im running sidekiq with the command

 sidekiq -q default -q mailer

Sidekiq.rb

config = YAML.load(ERB.new(IO.read(Rails.root + 'config' + 'redis.yml')).result)[Rails.env].with_indifferent_access

redis_conn = {url: "redis://localhost:6379/0"}

Sidekiq.configure_server do |s|
  s.redis = redis_conn
end

Sidekiq.configure_client do |s|
  s.redis = redis_conn
end

Sidekiq Enqueued jobs in mailer queue but not sending it forward.

Answer 1

This happens because ActionMailer uses the mailers queue as default queue to send emails.

Sneakers also using mailers queue to send emails by default. But there is no Worker for queue named mailers.

By adding the following line in my application.rb solved my issue.

config.action_mailer.deliver_later_queue_name = 'default'
