Paypal DoDirectPaymentRequest returning NULL - paypal

Question

I am using Paypal's classic API to do a Direct Payment. Here's the code:
require('merchant-sdk-php-master/samples/PPBootStrap.php');
$logger = new PPLoggingManager('DoDirectPayment');
$address = new AddressType();
$address->Name = $full_name;
$address->Street1 = $address_1;
$address->Street2 = $address_2;
$address->CityName = $city;
$address->StateOrProvince = $province;
$address->PostalCode = $postal_code;
$address->Country = $country;
$address->Phone = $phone;
$paymentDetails = new PaymentDetailsType();
$paymentDetails->ShipToAddress = $address;
$paymentDetails->OrderTotal = new BasicAmountType('CAD', $amount);
$personName = new PersonNameType();
$personName->FirstName = $first_name;
$personName->LastName = $last_name;
$payer = new PayerInfoType();
$payer->PayerName = $personName;
$payer->Address = $address;
$payer->PayerCountry = $country;
$cardDetails = new CreditCardDetailsType();
$cardDetails->CreditCardNumber = $card_number;
$cardDetails->CreditCardType = $card_type;
$cardDetails->ExpMonth = $expiry_month;
$cardDetails->ExpYear = $expiry_year;
$cardDetails->CVV2 = $cvv;
$cardDetails->CardOwner = $payer;
$ddReqDetails = new DoDirectPaymentRequestDetailsType();
$ddReqDetails->CreditCard = $cardDetails;
$ddReqDetails->PaymentDetails = $paymentDetails;
$ddReqDetails->PaymentAction = 'Sale';
$ddReqDetails->IPAddress = $ip_address;
$ddReqDetails->ReturnFMFDetails = true;
$doDirectPaymentReq = new DoDirectPaymentReq();
$doDirectPaymentReq->DoDirectPaymentRequest = new DoDirectPaymentRequestType($ddReqDetails);
$logger->info("created doDirectPaymentReq Object");
$paypalService = new PayPalAPIInterfaceServiceService();
try{
$doDirectPaymentResponse = $paypalService->DoDirectPayment($doDirectPaymentReq);
var_dump($doDirectPaymentResponse);
}
catch (Exception $ex){
var_dump($ex);
}
This is the object it returns:
object(DoDirectPaymentResponseType)#84 (15) { ["Amount"]=> NULL ["AVSCode"]=> NULL ["CVV2Code"]=> NULL ["TransactionID"]=> NULL ["PendingReason"]=> NULL ["PaymentStatus"]=> NULL ["FMFDetails"]=> NULL ["ThreeDSecureResponse"]=> NULL ["PaymentAdviceCode"]=> NULL ["Timestamp"]=> NULL ["Ack"]=> NULL ["CorrelationID"]=> NULL ["Errors"]=> NULL ["Version"]=> NULL ["Build"]=> NULL } ­
I'm Canadian so I can't use the new API's because they're not available here yet. I'm stuck with the classic API. Why am I getting this result?
Any help is appreciated!

For some reason, yesterday I was getting an object of NULL values. However, today I am getting an error message. I fixed the error and received a success.
Why it was showing me the error message today and not yesterday, I do not know. I never changed any of the code so it must have been something on Paypal's end.
Still have no idea what was wrong, but that's that.
