Hello.
Protocol 4 enabled for sagepay - "omnipay/sagepay": "^4.0",

Getting this error back after posting to Server...
3120 : The DeliveryFirstnames field is required.

But my card object is initialised like so below...
Anyone see what the problem might be?
I can't see any reference to 'DeliveryFirstnames 'in the omnipay code.

$card = new CreditCard([
    // 'firstName' => $customer->firstname,
    // 'lastName' => $customer->lastname,
    'billingFirstName' => $customer->firstname,
    'billingLastName' => $customer->lastname,
    'billingAddress1' => isset($billingData[0]) ? $billingData[0]: '',
    'billingAddress2' => isset($billingData[1]) ? $billingData[1]: '',
    'billingAddress3' => isset($billingData[2]) ? $billingData[2]: '',
    'billingCity' => $billing->city,
    'billingPostcode' => $billing->zip,
    'billingCountry' => $billing->country->code, // 'GB',
    // 'billingPhone' => '01234 567 890',
    'email' =>  $customer->user->email,
    // 'shippingFirstnames' => $customer->firstname,
    // 'shippingFirstNames' => $customer->firstname,

    // 'ShippingFirstNames' => $customer->firstname,
    // 'deliveryFirstnames' => $customer->firstname,

This was just a case of confusing error message.
"shippingFirstName" works.
