I am using the most current Force.com Toolkit for PHP provided at https://developer.salesforce.com/page/PHP_Toolkit to do this API push. I can authenticate and query salesforce without any issue, however when I attempt to create a lead, Salesforce responds back with an error "Unable to find a deserializer for the type common.api.soap.wsdl.QueryResult Error Id: 39234132-20621 (-848058548)"

Here is the SOAP data we are sending salesforce:
 
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"

</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
 
And here is the SOAP response from Salesforce:
 
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<soapenv:Fault>

<faultstring>Unable to find a deserializer for the type common.api.soap.wsdl.QueryResult Error Id: 39234132-20621 (-848058548)</faultstring>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
