Get Client Domains

The "response" of sites_web_domain_get is always empty.
The group_id (catched with "client_get_groupid") is correct and there is a domain in the table for sys_groupid (type vhost)
Even if I pass domain_id directly or pass an empty array for domain_id , the response is still empty.
Is there another filter in the function which can block possible results.
Other functions work fine: client_add, client_get, sites_web_domain_add, ...

 

what about function domains_get_all_by_user($session_id, $group_id) ?

 

domains_get_all_by_user works, but delivers the content of table "domain". I would like the content of "web_domain".
Could using REST API causing that problem?

 

i can use sites_web_domain_get($session_id, 525);
or
sites_web_domain_get($session_id,(array('domain' => 'example.com')));
without any problems.
for all web-domains on one server: sites_web_domain_get($session_id,(array('server_id' => '37')));

 

Also working with REST ? I now checked with SOAP and it worked. The following REST example worked until now very good except the function "sites_web_domain_get"
https://git.ispconfig.org/ispconfig/ispconfig3/commit/9376d70f0ccba49ead95ef47f0ecba568ea2d6e1
Is there an Bug with the REST wrapper?

 

restCall('sites_web_domain_get', array('session_id' => $session_id, 'primary_id' => array('server_id' => '37')));

is the same as

sites_web_domain_get($session_id,(array('server_id' => '37')));

 

I found the problem:
I used domain_id which is the primary instead of primary_id
restCall("sites_web_domain_get", array('session_id' => $this->session_id, 'domain_id' => array('sys_groupid' => $this->client_group_id) ));
Now:
restCall("sites_web_domain_get", array('session_id' => $this->session_id, 'primary_id' => array('sys_groupid' => $this->client_group_id) )); is working
thx a lot.
