Error message:
Does not perform grafana query against Checkmk

Output of “cmk --debug -vvn hostname”: (If it is a problem with checks or plugins)
Hello, because I wanted to test the plugin version 3.0.0.0 of Checkmk for Grafana, I have tried it without https certified connections, simply by http, the datasource works connected but when trying to make a dashboards I see that it does not complete it, the version of grafana that I use is version 9.4.7 and the error is attached in the screenshot, does not complete the connection to make the query

Have you tried this or does it depend on a version of grafana? if so, which is the valid version of Grafana?

Thank you very much
