We discovered that the params are being silently filtered out, which is causing the lack of error. One idea is to throw validation errors in the controller. However, it seems the "Rails way" is to keep the controller light and rely on model validations. Model validations are conditional and have custom messages, so perhaps we can permit all ACS potential params and remove the conditional param filtering.
