I'm using the PHP SDK 2020_2 version. I'm getting the following error:`*Fatal error*: Uncaught SoapFault exception: [<soapenv:Server.userException>] The request could not be understood by the server due to malformed syntax. in /var/www/vhosts/shop.xxx.com/httpdocs/tools/netsuite/PHPToolkit/NSPHPClient.php:296 Stack trace: #0 /var/www/vhosts/shop.xxx.com/httpdocs/tools/netsuite/PHPToolkit/NSPHPClient.php(296): SoapClient->__soapCall('get', Array, NULL, Array) #1 /var/www/vhosts/shop.xxx.com/httpdocs/tools/netsuite/PHPToolkit/NetSuiteService.php(157055): NSPHPClient->makeSoapCall('get', Object(GetRequest)) #2 /var/www/vhosts/shop.geistlich-na.com/httpdocs/tools/netsuite/outbound/add_order.php(8): NetSuiteService->get(Object(GetRequest)) #3 /var/www/vhosts/shop.xxx.com/httpdocs/tools/netsuite/index.php(36): include('/var/www/vhosts…') #4 {main} thrown in /var/www/vhosts/shop.geistlich-na.com/httpdocs/tools/netsuite/PHPToolkit/NSPHPClient.php on line *296*`
