How to work with this complicated namespace?

[gelinger777]

Hi There @CodeDredd . Thanks for your great package. I can't yet figure out how can I make a request to this https://ec.europa.eu/taxation_customs/tedb/ws/VatRetrievalService.wsdl

$soapResponse = Soap::baseWsdl('https://ec.europa.eu/taxation_customs/tedb/ws/VatRetrievalService.wsdl')
        ->withOptions([
            'trace' => true,
             'debug'=>true
           
        ])
        ->call('RetrieveVatRates',[
            'memberStates' => 'AT',
   
        ]);

             
 
        var_dump($soapResponse->getBody() );

Then I get

CodeDredd\Soap\Client\Events\ConnectionFailed::__construct(): Argument #1 ($request) must be of type CodeDredd\Soap\Client\Request, null given, called in /home/amepheas/Desktop/gyg_laravel/gyg_proxy_laravel/vendor/codedredd/laravel-soap/src/SoapClient.php on line 540
