Неперехваченное исключение SoapFault: [soapenv: Receiver] java .lang.NullPointerException

Question

Это XML, который мне нужно ввести PHP код:

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:rat="http://ws.estesexpress.com/ratequote" xmlns:rat1="http://ws.estesexpress.com/schema/2019/01/ratequote">

      </rat:auth>
   </soapenv:Header>
   <soapenv:Body>
      <rat1:rateRequest>

            <rat1:countryCode>US</rat1:countryCode>
            <rat1:postalCode>23229</rat1:postalCode>
            <rat1:city>henrico</rat1:city>

         </rat1:pickup>
         <rat1:declaredValue>1500.00</rat1:declaredValue>

         <rat1:baseCommodities>
            <rat1:commodity>
               <rat1:class>50</rat1:class>
               <rat1:weight>1000</rat1:weight>
            </rat1:commodity>
         </rat1:baseCommodities>
      </rat1:rateRequest>
   </soapenv:Body>
</soapenv:Envelope>

Вот мой PHP код:

$params = array('soap_version'   => SOAP_1_2, 'compression' => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP, 'encoding'=>'UTF-8', 'trace' => 1, 'exceptions' => true, 'cache_wsdl' => WSDL_CACHE_NONE, 'features' => SOAP_SINGLE_ELEMENT_ARRAYS);

$arg= array(     
   
            'auth'=>array(
                    'user'     =>'user',
                    'password' =>'password',
            ),

      //'rateRequest'=>array(
            'requestID'=>'test',
            'account'=>'0243733',
        
            'originPoint'=>array( //originpoint
                                    'countryCode'=>'US',
                                    'postalCode'=>'23229',
                                    'city'=>'henrico',
                                    'stateProvince'=>'va',
                                ),
        
            'destinationPoint'=> array(//destination
                                    'countryCode'=>'US',
                                    'postalCode'=>'94610',
                                    'city'=>'oakland',
                                    'stateProvince'=>'ca',
                                        ),
        
                'payor'=>'S', // I try S, C but same issue " java.lang.NullPointerException ".
                'terms'=>'P',
        
            'pickup'=> array('date'=>'2019-01-30'),        
            
            'declaredValue'=>1500.00,
        
            'declaredValueWaived'=>'N',
        
            'stackable'=>'N',
        
            'linearFeet'=>5,
        
            'foodWarehouse'=>'Publix',
    
            'commodity'=>array(
                                'class'=>50,
                                    'weight'=>1000,
            ),
        //   ),//end of rateRequest     
    );//end of header

$soapRequest = new SoapClient("https://www.estes-express.com/tools/rating/ratequote/v4.0/services/RateQuoteService?wsdl",$params);

$response=$soapRequest->getQuote($arg);

var_dump($response);

Я получаю эту ошибку :

Неперехваченное исключение SoapFault: [soapenv: Receiver] java .lang.NullPointerException "
