When a payment error happens during checkout the customer is not being about errors when processing the payment.

The error response looks like this:

Array
(
    [customer] => Array
        (
            [billing] => Array
                (
                    [city] => ....
                    [company] => .....
                    [country_code] => FR
                    [house_no] => 
                    [state] => ....
                    [street] => .....
                    [zip] => ....
                )
            [customer_ip] => ....
            [customer_no] => ....
            [email] => .....
            [first_name] => ....
            [gender] => ....
            [last_name] => .....
        )

    [result] => Array
        (
            [additional_message] => 51 Not sufficient funds
            [status] => FAILURE
            [status_code] => 406012
            [status_text] => Insufficient funds or credit limit exceeded
        )

    [transaction] => Array
        (
            [amount] => 0
            [currency] => EUR
            [date] => 2024-06-14 11:55:46
            [order_no] => .....
            [payment_data] => Array
                (
                    [card_brand] => VISA
                    [card_expiry_month] => ..
                    [card_expiry_year] => ..
                    [card_holder] => ..........
                    [card_number] => XXXXXXXXXXXX
                    [last_four] => 
                )

            [payment_type] => CREDITCARD
            [status] => FAILURE
            [status_code] => 406012
            [test_mode] => 0
            [tid] => 
        )

)

In this case, the customer is confused not getting any info and checkout just hangs:
