make work pasarella to payment local (chile) webpay and oneclic

the oneclick payment gateway works well until the redirectfinal when the payment was already made, that redirect fails before it did not fail now if the webpay also worked but now there is an object called response that is not taking it and it falls when you start the payment process the server is in heroku la web is done with ruby on rails I need additional validations of select ones that are not related and that would be all and the certificates are for production environment
