Weird Parameter Behavior on Zabbix API

[artrune]

Hello! Hope you are doing well.

I've encountered something weird while testing the host.get method on the zabbix api, the selectItems parameter doesnt seem to work (It only works if i use extend, but I just want one property and not the whole output)

{
    "jsonrpc": "2.0",
    "method": "host.get",
    "params": {
                "output": ["hostid","name"],
                "selectItems": "itemid",
                "selectParentTemplates": ["templateId", "name"],
                "selectGroups": "groupid"
    },
    "auth": "xxxx",
    "id": 1
}

Any clues, or ideas? The other selects do run fine.

Running Zabbix 5.0.2

Turns out if i modify the select to

 "selectItems": ["itemid", "key_"],

It then works.
