Unable to represent properties from hash since grape v0.12.0

[RinkeRiezebos]

Hi there,

In advance: Please let me know if this is the wrong place to report this issue, it might be better to report at the representable gem or grape gem.

The issue: Since the update of the grape gem from v0.11.0 (still works) to v0.12.0 (doesn't work) I am unable to represent values from a hash using Grape-Roar, eg:

Gems:

• roar (1.0.1)
• grape (0.11.0)
• grape-entity (0.4.5)
• grape-roar (0.3.0)

module API
    module V1
        module Representers
            module SomeRepresenter 
                include Roar::JSON
                include Roar::Hypermedia
                include Grape::Roar::Representer

                property :some_property
            end
        end
    end
end

Throws:

> undefined method `some_property' for #<Hash:0x007f9f5b281318>
