The PaymentValidationErrors dictionary represents objects providing information about any and all errors that occurred while processing a payment request. When validation of the PaymentResponse returned by the PaymentRequest.show() or PaymentResponse.retry() methods fails, your code creates a PaymentValidationErrors object to pass into retry() so that the user agent knows what needs to be fixed and what if any error messages to display to the user.

error Optional

A general description of a payment error from which the user may attempt to recover by retrying the payment, possibly after correcting mistakes in the payment information. error can be provided all by itself to provide only a generic error message, or in concert with the other properties to serve as an overview while other properties' values guide the user to errors in specific fields in the payment form.

paymentMethod Optional

Any payment method specific errors which may have occurred. This object's contents will vary depending on the payment method used.
