Should fail with original error

In some cases original exceptions have important effects, for example I ran with issue that this fix is not working with jsonapi-resources "deallocate prepared statements if we fail inside a transaction"(https://github.com/rails/rails/pull/22170), so when you shallow error here you'd potentially breaks some other logic.

I think you should propagate original error, not just ActiveRecord::Rollback

Something like this should work, I think
https://github.com/cerebris/jsonapi-resources/blob/v0.9.0/lib/jsonapi/operation_dispatcher.rb#L30:
rollback(transactional) if results.has_errors? => fail results.original_error if results.has_errors? && transactional

Inizia da operation_dispatcher.rb intorno alla riga 30 e acts_as_resource_controller.rb intorno alla riga 100, quindi esamina il comportamento transazionale indicato nella modifica Rails collegata. Verifica che un'operazione transazionale propaghi la propria eccezione originale invece di propagare solo ActiveRecord::Rollback, mentre il comportamento non transazionale rimane invariato.
