Thank you for reaching out.

I can confirm that following input data:

{
    "data": [
        {
            
            "attr": {
                "name": "hello",
                "radio_bands": [
                    {
                        "enabled_alarms": "1C00",
                        "transceiver": 45.0
                    },
                    {
                        "enabled_alarms": "1C00",
                        "transceiver": 45.0
                    },
                    {
                        "enabled_alarms": "0C00",
                        "transceiver": 51.0
                    }
                ]
            }
        }
    ]
} 

with JSONPath:

$..[?(@.name=="hello")].radio_bands[*~]

Works under https://jsonpath.com/ but does not work with Zabbix 6.0.4 JSONPath preprocessing engine:

Try it with JSONPath:

$..[?(@.name=="hello")].radio_bands.*~

Anonymouse aigars.kadikis it is possible to get the keys of the array elements with JsonPath in Zabbix. Namely:

$..[?(@.name=="hello")].radio_bands.*~

As per documentation of Zabbix:

• Matched element names can be extracted by adding a ~ suffix to the JSONPath. It returns the name of the matched object or an index in string format of the matched array item. The output format follows the same rules as other JSONPath queries - definite path results are returned 'as is' and indefinite path results are returned in array. However there is not much point of extracting the name of an element matching a definite path - it's already known.

This is the case as we do not support JsonPath Plus specification, but we do support the ~ extension.
