Rails Trailblazer Reform: `initialize': uninitialized constant Uber::Options (NameError)

Question

Im trying to get Trailblazer-Rails to work in my rails project.

But there seem to be some weird things going on with the reform gem.

I cant start rails with "rails s". It responds with the error:

"/home/dragonslayer/.rvm/gems/ruby-2.3.1/gems/reform-2.2.3/lib/reform/form/populator.rb:12:in `initialize': uninitialized constant Uber::Options (NameError) "

but when i remove my contract, it works. When i remove the conctract it sometimes seem to not be able to find my Operation.

My operation looks like this:

class GuildApplication::Create < Trailblazer::Operation

 step Model( GuildApplication, :new)
 step Contract::Build( constant: GuildApplication::Contract::Create)
 step Contract::Validate()
 step :set_status_to_pending
 step Contract::Persist()

 def set_status_to_pending(options)
  options["model"].status = :pending
 end
end

My contract:

module GuildApplication::Contract
 class Create < Reform::Form

  property :first_name
  property :last_name
  property :email
  property :username
  property :server
  property :spec
  property :armory
  property :klass
  property :played
  property :klass_played
  property :bio
  property :raid_experience
  property :reason
  property :old_guild
  property :progress_raid
  property :attendance
  property :other

  property :screenshot, virtual: true

  extend Paperdragon::Model::Writer
  processable_writer :image
  property :image_meta_data

  validates :first_name, :last_name, :email, :username, :server, presence: true
  validates :screenshot, file_size: { less_than: 2.megabytes}, file_content_type: { allow: ['image/jpeg', 'image/png'] }
  validates_uniqueness_of :email
  validates_uniqueness_of :username
 end
end

My Controller:

class GuildApplicationsController < ApplicationController

 def new
  render html: cell(GuildApplication::Cell::Register, nil, layout: Familylegion::Cell::LandingPage)
 end

 def create
  run GuildApplication::Create
 end
end

My gemfile:

source 'https://rubygems.org'

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
 "https://github.com/#{repo_name}.git"
