I'm currently running 2.1.3 and utilizing Braintree processing at checkout. Currently, if a customer places an error with a bad credit card, wrong CVV number, or wrong address, they just get the error of
An error occurred on the server. Please try to place the order again.
What do I need to change in PaymentInformationManagement.php to override this and show the actual reason for decline? Such as card declined, cvv error, address error, etc.
