I want to add x custumers on Prestashop via code but with extra fields

[Stefan Burghelea]

I'm trying to add customers with a code but the PrestaShop is giving me a bug. Im using PHP and XML

Code:

 $XMLRQString = '<?xml version="1.0" encoding="utf-8"?>'.
                    '<x:Winmax4GetEntitiesRQ xmlns:x="urn:Winmax4GetEntitiesRQ">'.
                    '</x:Winmax4GetEntitiesRQ >';
                    $Params=array(
                    'CompanyCode'=>'',
                    'UserLogin'=>'',
                    'UserPassword'=>'',
                    'Winmax4GetEntitiesRQXML'=> $XMLRQString
                    );
                    $return = $client->GetEntities($Params);
                    $XMLRSString = new SimpleXMLElement($return->GetEntitiesResult);

            foreach ($XMLRSString->Entities->Entity as $entity)
            {   
                    $default_lang= Configuration::get('PS_LANG_DEFAULT');

                    $customer=new Customer();

                    $customer->email= $entity->Email;

                    $customer->lastname= $entity->EntityType;

                    $customer->firstname= [$default_lang => $entity->Name];

                    $customer->contribuinte= $entity->TaxPayerID;

                    $customer->passwd= $entity->TaxPayerID;

                    $customer->active = 1;

                    $customer->add();
            }

ERROR:
