undefined method `map' for nil:NilClass for association

[noctivityinc]

Here is my model:

class UserDeviceOffer < Base
  include Her::Model
  include_root_in_json true
  parse_root_in_json true, format: :active_model_serializers
  collection_path "users/:user_id/user_device_offers"
  resource_path "user_device_offers/:id"
  request_new_object_on_build true

  belongs_to :user
  # has_one :device, :class_name => "Device", :foreign_key => "user_device_offer_id"

end

and when I try to interact with it in any way I get the above error, which points to here:

  # @private
        def instantiate_collection(klass, parsed_data = {})
          records = klass.extract_array(parsed_data).map do |record|
            instantiate_record(klass, data: record)  ## FAILS ON THIS LINE
          end
          Her::Collection.new(records, parsed_data[:metadata], parsed_data[:errors])

Do you have a sample response and the call which is producing the error?

@zacharywelch was that what you were looking for? Here's even more logs:

That should be enough @noctivityinc. Not sure why a separate request is made to pick up the first device offer since they should be cached after .all. Tied up at the moment but I'll try and reproduce later.

[noctivityinc]

Any update on this? Were you able to reproduce?

@zacharywelch figured it out. Since the model is UserDeviceOffers the serialized json root is userdeviceoffersso I needed to add:

parse_root_in_json :userdeviceoffers
