Error with Goliath & BarrierAroundware

README

This gist is an example of an error I'm seeing on a much larger Goliath app.  There are two issues:

1: The 'body' variable in the aroundware seems to be receiving the desired body converted to an array.
2: The presence of the aroundware generates a 2nd 500 response due to "received response for a non-pending request!"

Thanks.

* Note:  The response is the entire response received.  It gets cut off.

aroundware_test.rb

require 'rubygems'
require "bundler"
Bundler.setup
Bundler.require(:default)
require 'json'

class MyCustomAroundware
  include Goliath::Rack::BarrierAroundware
  
  def pre_process
    return Goliath::Connection::AsyncResponse
  end
  
  def post_process
    puts status
    puts headers
    puts body
    [status, headers.merge("Content-Type" => "application/json"), body.to_json]
  end
  
end

class HelloWorldEndpoint < Goliath::API
  def response(env)
    [200, {}, {:message => "Hello World"}]
  end
end

class AroundwareTest < Goliath::API
  use Goliath::Rack::BarrierAroundwareFactory, MyCustomAroundware
  
  map "/hello", HelloWorldEndpoint
  
end
