LLD host discovery

[akam]

Hello, I am trying to do LLD host discovery based on the item output on hosts. (Zabbix 6.4)

I have created a new template with the item 'Dispatcher hosts discovery' which returns JSON like this:

{
  "jsonrpc":  "2.0",
  "result": {
    "NRSETS": 2,
    "RECORDS":  [{
        "SET":  {
          "ID": 111,
          "TARGETS":  [{
              "DEST": {
                "URI":  "sip:1.1.1.1",
                "FLAGS":  "IP",
                "PRIORITY": 0,
                "LATENCY":  {
                  "AVG":  0,
                  "STD":  0,
                  "EST":  0,
                  "MAX":  0,
                  "TIMEOUT":  5
                }
              }
            }]
        }
      }, {
        "SET":  {
          "ID": 999,
          "TARGETS":  [{
              "DEST": {
                "URI":  "sip:2.2.2.2",
                "FLAGS":  "AP",
                "PRIORITY": 0,
                "LATENCY":  {
                  "AVG":  42,
                  "STD":  0,
                  "EST":  42,
                  "MAX":  42,
                  "TIMEOUT":  0
                }
              }
            }, {
              "DEST": {
                "URI":  "sip:8.8.8.8",
                "FLAGS":  "AP",
                "PRIORITY": 0,
                "ATTRS":  {
                  "BODY": "zabbix-host=TODO-extract-hostname-from-here",
                  "DUID": null,
                  "MAXLOAD":  0,
                  "WEIGHT": 0,
                  "RWEIGHT":  0,
                  "SOCKET": null,
                  "SOCKNAME": null,
                  "OBPROXY":  null
                },
                "LATENCY":  {
                  "AVG":  27,
                  "STD":  0,
                  "EST":  27,
                  "MAX":  27,
                  "TIMEOUT":  0
                }
              }
            }]
        }
      }]
  },
  "id": 4043662
}

I created a discovery rule dependent item with LLD macros and a host prototype



$.result.RECORDS[?(@.SET.ID==999)].SET.TARGETS.*.DEST.URI returns ["sip:2.2.2.2", "sip:8.8.8.8"]



And I created a simple host prototype

And I can see the error


Is it necessary to have "data" in output JSON? is there any workaround to fix it?

I might be wrong but I think the replace is creating the error? I've never used it myself but seems that the syntax is like this:


So I wonder if it works when you remove the replace or change it with replace({#DISPATCHER_HOST},"sip:","")

I have changed LLD macros {#DISPATCHER_HOSTNAME} to $.result.RECORDS[?(@.SET.ID==999)].SET.TARGETS.*.DEST.FLAGS, so output now is like ["AP","AP"]
and set the host prototype to {{#DISPATCHER_HOST}.regsub(""([A-Z].*)"", \1)} to remove "
but still the same error
