Invalid option :in provided for field

[justincy]

Running bundle exec rake db:migrate gives me this error

rake aborted!

Problem:
  Invalid option :in provided for field :record_type.
Summary:
  Mongoid requires that you only provide valid options on each field definition in order to prevent unexpected behaviour later on.
Resolution:
  When defining the field :record_type on 'Freereg1CsvFile', please provide valid options for the field. These are currently: as, default, identity, label, localize, metadata, pre_processed, subtype, type, versioned. If you meant to define a custom field option, please do so first like so:

   Mongoid::Fields.option :in do |model, field, value|
     # Your logic here...
   end
   class Freereg1CsvFile
     include Mongoid::Document
     field :record_type, in: true
   end
