... serialized_animals = ActiveModel::Serializer::CollectionSerializer.new(animals, each_serializer: ApiHandler::Api::Private::MobileApp::V8::AnimalSerializer)
aggregate_failures 'response details' do
expect(JSON.parse(response.body)['data']['animals']).to(eq(JSON.parse(serialized_animals.to_json)))
end ...
The AnimalSerializer sits in animal_engine/app/serializers/api_handler/api/private/mobile_app/v8
Weirdly serializing a single item works.
I get the following error
UncaughtThrowError: uncaught throw :no_serializer
Use :serializer instead of :each_serializer. Not sure why it was failing but that fixes it.
