Display Stripe errors to clients
Right now when there's an error during checkout or when client adds credit card in "manage credit card", Stripe module displays a generic error and says to contact support.
The Stripe error response already includes an actual description of an error:
error => Your card's security code is incorrect.
Can you please display this error to the client at the time when error occurs? This will eliminate multiple tickets from clients asking about the error, and it will help save sales that might be abandoned because client gets frustrated entering credit card and getting error.
Your module already tracks Stripe's error response to display generic error, so all you have to do is return or echo error description to the client. A quick fix that will help save a lot of lost money!
