Get the list of hosts of the parent group

[SyDemon]

Hello.
I use the following device distribution scheme for the groups:




I need to build a pie chart showing the ratio of the devices in the ALL/GrA and ALL/GrB groups.
For this purpose I use API to get ZABBIX server data by running the following script:

hosts()
{
JSON='
{
"jsonrpc": "2.0",
"method": "host.get",
"params": {
"output": [
"hostid ",
"host"
],
"groupids": '23'
},
"auth": "'$TOKEN'",
"id": 1
}

If I specify the ID of the ALL / GrA / R1 group in the query, I get the list of the hosts this group contains. If I specify the group ID of ALL / GrA, an empty value is returned.
Is this a bug or am I doing something wrong?
