Is this gem dead? Nothing seems to work.

[Loschcode]

I installed activemessaging and I'm trying to make it work with AmazonMQ right now, when I set it up it does not seem to subscribe at all to my topic.

Is this gem still working and maintained, or not at all?

# processor
class UpdateFrontendManifestProcessor < ApplicationProcessor

  subscribes_to :update_frontend_manifest

  def on_message(message)
    logger.debug "UpdateFrontendManifestTopicProcessor received: " + message
  end
end

# broker.yml
development:
    adapter: stomp
    login: "test"
    passcode: "my-pass"
    host: "address.amazonaws.com"
    port: 61614
    reliable: true

# messaging.rb
ActiveMessaging::Gateway.define do |s|
  s.destination :update_frontend_manifest, '/topic/update_frontend_manifest'
end
