Jsonpath in dependent item prototype

[zabbixuserfk]

Hello there,

I'm trying to get the "device-status" for each device from a json that I've (over)simplified here :

[
    {
      "device": {
        "device-name": "toto",
        "device-status": "Online"
      }
    },
    {  
      "device": {
        "device-name": "titi",
        "device-status": "Online"
      }
    },
    {
      "device": {
        "device-name": "tata",
        "device-status": "Online"
      }
    }
]​

This json is returned by a zabbix agent item and I've made a LLD on that master item.
Nothing fancy here except a {#DEVICE_NAME} LLD macro with the jsonpath $.device.['device-name'] (see attachment 1) on which I can base my dependent item prototype defined as seen on attachment 2.
The items have been created, but I struggle to find the right jsonpath for the preprocessing of my item prototype (see attachment 3)... None of these seem to be correct, as I don't get any data in Zabbix or get the following error : 1. Failed: cannot extract value from json by path "$.[?(@.device['device-name']=="toto")].['device-status']": no data matches the specified path

$.[?(@.device['device-name']=="{#DEVICE_NAME}")].['device-status']
$.[?(@.device.['device-name']=="{#DEVICE_NAME}")].['device-status']
$.device[?(@.['device-name']=="{#DEVICE_NAME}")].['device-status']
$.device.[?(@.['device-name']=="{#DEVICE_NAME}")].['device-status']

Funny thing : With this syntax, my items aren't unsupported, but simply empty...

$.[?(@.device.['device-name']=="{#DEVICE_NAME}")].['device-status']


I've used similar syntaxes in the past, but I don't get where my error is. Could someone see it and help me please ?

device-name and device-status are same level items... so you really cannot form a path like device.device-name.device-status...

I've finally managed to do it with :

$..[?(@['device-name'] == "{#DEVICE_NAME}")].['device-status']

Have to bookmark it... I always struggle with jsonpath... It just does not agree with me..
