Zabbix API - hostgroup.get

[debcen]

День Добрый, с помощью API пытаюсь получить ID групп и имена:
$json = {
jsonrpc => "2.0",
method => "hostgroup.get",
params =>
[
nodeids => 0,
monitored_hosts => 1,
output => "groupid", "name",
preservekeys => 1,
],
id => 2,
auth => "$authID",
};

выдает только ID группы, название не хочет

output=['name']

params =>
[
nodeids => 0,
monitored_hosts => 1,
output => ["name"],
preservekeys => 1,
],
id => 2,
auth => "$authID",
};
не хочет,
Use of uninitialized value in print at
