Issue Error 1019 when creating subscription with plesk api

[greek_batter]

I am trying to create a subscription account with plesk api. When I create it with "website" type (with physical folders) despite the subscription is being created it returns me an error "error 1019 Incorrect name arisolecom.com. This domain name already exists." . Ofcourse this does not exist and it never existed in the past. Looking at my log I have the impression that it is called twice but I cant be certain.If I choose forward type then the subscription is normally being created. I tried different libraries and always there is this outcome. Here is my code:

$client = new PleskApiClient($host);
$client->setCredentials($login, $password);

$request = <<<EOF
<packet>
<webspace>
<add>
<gen_setup>
<name>arisolecom.com</name>
<ip_address>92.92.92.92</ip_address>
</gen_setup>
<hosting>
<vrt_hst>
<property>
<name>ftp_login</name>
<value>test-login3</value>
</property>
<property>
<name>ftp_password</name>
<value>test-password</value>
</property>
<ip_address>92.92.92.92</ip_address>
</vrt_hst>
</hosting>
</add>
</webspace>
</packet>
EOF;

$response = $client->request($request);
echo $response;

I am using this source: https://github.com/plesk/api-examples/tree/master/php And my plesk version is plesk 12.5.30
