Failed: cannot extract value from json by path

Hi,

perhaps someone could give me a hint.

Trying to extract a value from this json source

{
"Body" : {
"Data" : {
"DAY_ENERGY" : {
"Unit" : "Wh",
"Value" : 735.70000000000005
},
"DeviceStatus" : {
"ErrorCode" : 307,
"StatusCode" : 3
},
"TOTAL_ENERGY" : {
"Unit" : "Wh",
"Value" : 4398
},
"YEAR_ENERGY" : {
"Unit" : "Wh",
"Value" : 4398.3999999999996
}
}
},
"Head" : {
"RequestArguments" : {
"DataCollection" : "CommonInverterData",
"DeviceClass" : "Inverter"
},
"Status" : {
"Code" : 0
},
"Timestamp" : "2021-12-12T22:19:48+01:00"
}
}

but always getting this error message

Preprocessing failed for: {. "Body" : {. "Data" : {. "DAY_ENERGY" : {. "Unit" : "Wh",. ...
1. Failed: cannot extract value from json by path "$.": jsonpath was unexpectedly terminated"

1) I created a http agent with fetches the json data. The history data of that item looks good.
2) Next I created a dependent item with a JsonPath preprocessing parameters $.Body.Data.DAY_ENERGY.Value
3) The test with the history data works fine.

Any ideas or a bug?
I'm running zabbix 6.0.0 alpha7

(Nevermind, error was gone with the update to zabbix-server 6.0.0. beta1)

Seems to be related to the zabbix-proxy.
Changes in the preprocessing are not transferred directly. After restarting the proxy new values are transferred directly.
