Alert Manager Plugin Grafana 8.2.X

Hi

I’ve ran into a problem while trying to add the native Alert Manager plugin (currently in alpha state) for our Grafana stack.

After upgrading Grafana from 7.5.10 to 8.2.5 and setting the enable_alpha plugins setting to true I added the Datasource in the WebUI with a successful health-check. On the Alert Manager Backend I could see the health-check requests.

When I select Alert groups (Alpha) on a new panel and select the new Datasource no data is present and no request are generated to the backend whatsoever.

Is this a bug or am I doing something wrong here? Can someone help me out?

Cheers!
