Checkmk data source API problem

CMK version: 2.2.0p23.cre
OS version: Ubuntu 22.04

Error message: INFO [07-01|12:51:43] Request Completed logger=context userId=1 orgId=1 uname=admin method=GET path=/api/datasources/proxy/uid/edqfmqmdgpm2oc/rest/check_mk/api/1.0/version status=404 remote_addr=192.168.65.1 time_ms=6 duration=6.871103ms size=196 referer=http://localhost:3000/connections/datasources/edit/edqfmqmdgpm2oc handler=/api/datasources/proxy/uid/:uid/* status_source=server

I’m encountering an issue with the REST API; they are telling me there might be a problem with the versions or the edition of Checkmk. I tried getting the latest version of the Grafana Checkmk Datasource plugin, version 3.3.0 (more precisely this plugin: https://github.com/Checkmk/grafana-checkmk-datasource/releases/download/v3.3.0/tribe-29-checkmk-datasource-3.3.0.zip) . Despite this, it seems that the API route isn’t up-to-date. Consequently, I’m unable to connect my Checkmk server to Grafana v11.1.0.

Should I wait for a plugin update? Or is there possibly an error in how I’m setting things up?

Thanks.

Hello
Please, check your config. It seems you are using Checkmk 2.2.0p23 Raw edition (cre), so you must fill this information:
URL: http:///
Edition: Raw Edition
Version: >= 2.2
Also check the credentials you are using.
