xml — Переполнение стека ошибок службы SOAP Apex в Webtolead

Я хочу представить данные в ведущую форму в SFDC, вот мой код:

require_once ('soapclient/SforcePartnerClient.php');
require_once ('soapclient/SforceHeaderOptions.php');

// Salesforce.com credentials
$sfdcUsername = "SFDC_USERNAME";
$sfdcPassword = "SFDC_PASSWORD";
$sfdcToken = "SFDC_TOKEN";
// the email address to search for. could also use a post/get variable
//$searchEmail = '[email protected]';

$sfdc = new SforcePartnerClient();
// create a connection using the partner wsdl
$SoapClient = $sfdc->createConnection("soapclient/PartnerWSDL.xml");
$loginResult = false;

try {
// log in with username, password and security token if required
$loginResult = $sfdc->login($sfdcUsername, $sfdcPassword.$sfdcToken);
} catch (Exception $e) {
global $errors;
$errors = $e->faultstring;
echo "Fatal Login Error <b>" . $errors . "</b>";
die;
}

$parsedURL = parse_url($sfdc->getLocation());
define ("_SFDC_SERVER_", substr($parsedURL['host'],0,strpos($parsedURL['host'], '.')));
define ("_WS_NAME_", "WebToLeadServices2");
define ("_WS_WSDL_", "soapclient/" . _WS_NAME_ . ".xml");
define ("_WS_ENDPOINT_", 'https://' . _SFDC_SERVER_ . '.salesforce.com/services/wsdl/class/' . _WS_NAME_);
define ("_WS_NAMESPACE_", 'http://soap.sforce.com/schemas/class/' . _WS_NAME_);

$client = new SoapClient(_WS_WSDL_);
$sforce_header = new SoapHeader(_WS_NAMESPACE_, "SessionHeader", array("sessionId" => $sfdc->getSessionId()));
$client->__setSoapHeaders(array($sforce_header));

try {

$sObject = new stdclass();
$sObject->fullName = 'Smith';
$sObject->mobileNumber = '1234567896';
$sObject->emailAddress = '[email protected]';
$sObject->source = 'DIGITAL MARKETING';// call the web service via post
$wsParams=array('fullName'=>'rakesh shetty','mobileNumber'=>'1234567896','emailAddress'=>'[email protected]','source'=>'DIGITAL MARKETING');
$response = $client->createLeadFromWeb($sObject);
// dump the response to the browser
print_r($response);

// this is really bad.
} catch (Exception $e) {
global $errors;
$errors = $e->faultstring;
echo "Ooop! Error: <b>" . $errors . "</b>";
die;
}
