Errror SOAPACTION value when I call a webservice

Hello all,

When I call a WSDL in php, look this code :

// Standard SOAP header for username/password
// From http://stackoverflow.com/questions/13465168/php-namespaces-in-soapheader-child-nodes
class WSSESecurityHeader extends SoapHeader {
    public function __construct($username, $password)
    {
        $wsseNamespace = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-sece…';
        $security = new SoapVar(
            array(new SoapVar(
                array(
                    new SoapVar($username, XSD_STRING, null, null, 'Username', $wsseNamespace),
                    new SoapVar($password, XSD_STRING, null, null, 'Password', $wsseNamespace)
                ),
                SOAP_ENC_OBJECT,
                null,
                null,
                'UsernameToken',
                $wsseNamespace
            )),
            SOAP_ENC_OBJECT
        );
        parent::SoapHeader($wsseNamespace, 'Security', $security, false);
    }
}

// Key parameters for connecting to the web service:
$location = "http://IP:PORT/csp/dsa-cla-prd/com.siemens.med.hs.Country.WebServices.pats.ClassPatientServices.cls";
$uri = "http://intersystems.fr";
$username = "USER";
$password = "PASS";

// If the soap client is to be constructed from the WSDL, or if the WSDL is to be used to generate
// PHP classes (using various tools that exist for that purpose), ?WSDL=1 and the username/password
// need to be tacked on to the end of the URL:
$wsdl =  $location . "?WSDL=1&CacheUserName=" . $username . "&CachePassword=" . $password;
echo $wsdl.str_repeat('<br />', 4);

// Create SoapClient Object
$client = new SoapClient(null, array(
  "trace" => 1,
  "location" => $location,
  "uri" => $uri,
  "style" => SOAP_DOCUMENT,
  "use"  => SOAP_LITERAL)); 
 
// Add security header.
$client->__setSoapHeaders(new WSSESecurityHeader($username, $password));

//echo '<xmp>';
//print_r($client);
//echo '</xmp>';
// Object with parameter names and values for the SOAP call

try {
    $clsINOUTContext = new stdClass();
    $clsINOUTContext->AccessCode = 'ACC';
   
    $ClsOUTInfosPatient = new stdClass();

    $params = array(
            'clsINOUTContext' => $clsINOUTContext,
            'strINPatientIPP' => "11111111",
            'ClsOUTInfosPatient' => $ClsOUTInfosPatient
        );
   
    echo '<xmp>';
    print_r($params);
    echo '</xmp>';
   
   
    $return = $client->GetPatientInfo($params);
    var_dump($return);
} catch (Exception $e) {
    echo "Exception occured: " . $e;
}

I have this error :

Exception occured: SoapFault exception: [SOAP-ENV:Client] Erreur dans le WebService: Erreur interne détectée. ERROR #6207: Unexpected SOAPACTION value: http://intersystems.fr#GetPatientInfo in C:\wamp\www\clinicom_webservice\index.php:81 Stack trace: #0 C:\wamp\www\clinicom_webservice\index.php(81): SoapClient->__call('GetPatientInfo', Array) #1 C:\wamp\www\clinicom_webservice\index.php(81): SoapClient->GetPatientInfo(Array) #2 {main}

Can you help me ?
