Exception error="uninitialized constant V1" using Sneakers

Question

I'm trying to implement Sneakers, but I'm having some issues. Below you can find the code which subscribers to my queue and the actual error.

require 'sneakers'
require 'jwt'
require 'redis'
require 'json'


$redis = Redis.new(url: ENV['REDIS_URL'], password: ENV['REDIS_PASSWORD'])

class Processor
  include Sneakers::Worker
  QUEUE_NAME = :my_queue

  from_queue QUEUE_NAME

  def work(msg)
    message = JSON.parse(msg)
    if message["type"] == "error"
      $redis.incr "processor:#{err["error"]}"
    end

    controller = Object.const_get message['controller']
    action = message['method']
    controller.public_send(action, message['msg'])

    ack!
  end
end

Error:

[Exception error="uninitialized constant V1" error_class=NameError worker_class=Processor

The msg object

{\"controller\":\"V1::x::yController\",\"method\":\"my_method"\}

Any help is welcome, thank you!

Update

Even getting a simple Model such as my User is resulting into the same error.

[Exception error="uninitialized constant User"

I'm running the sneakers worker like so:

sneakers work UserCreate --require app/workers/user_create.rb
