What is the potential SOAP-Versionskonflikt issue mentioned in the forum thread?

The potential SOAP-Versionskonflikt issue mentioned in the forum thread is when different SOAP versions are used between the client and server, leading to compatibility issues. To solve this problem, you can explicitly specify the SOAP version to be used in the SOAP client options.

$options = array(
    'soap_version' => SOAP_1_2
);

$client = new SoapClient("http://example.com/wsdl", $options);
