Grafana no data

[nikossss]

A few days ago , I updated the zabbix from 6.0 to 6.2 Update Grafana 7.9 to 9.02, update plugins to 4.2.9 At the same time , I reinstall the grafana and grafana-zabbix plugin , but when I create the panel , I got this error By the way , my zabbix use Elasticsearch to store history data json: invalid use of ,string struct tag, trying to unmarshal unquoted value into int64

Also no data available. I updated to zabbix 6.0, everything worked. Now, after some weeks no data are available anymore.

Grafana: 9.0.4 Plugin: 4.2.9 Zabbix: 6.0.6

I removed the plugin, reinstalled it again. I created a new datasource, no success at all. No errors in the logs, what i can see in packet capture is the message

{"jsonrpc":"2.0","error":{"code":-32601,"message":"Method not found.","data":"Incorrect API \"application\"."},"id":2}

Please notice after during the creation of the datasource, i got confirmed, API version 6.0.6 was detected.

The method "application.get" is not available in the Zabbix documentation since 5.4. It seems it's finally gone.

I identified the root cause. Using only values in the query fields Host and Item will cause this issue. Using /*/ in the field Group additionally show data.
