Error while saving analytic unit. Datasource is not set

[spliakos]

I have the following configuration. Running hastic 0.5.0 and grafana app 0.5.0. Grafana version is 7.2.0 (In the screenshot you can see 7.1.3 but it's the same with 7.2.0.

Configuration in K8s is as follows:

So, as you can see in the screenshot, I'm trying to add an analytic unit, and when I'm pushing Create button, the error is "Error while saving analytic unit. Datasource is not set. If it's Grafana-test-datasource' then it's not supported.
This is strange, since when I add the Hastic DS in Datasources in Grafana, it looks like it's working, it returns that it's connected to the Datasource, and Hastic info is returned anyway as you can observe in the screenshot.

Is this a bug? Could it be something i'm not doing right?
This is the logs section from the hastic server:
kctl logs -f infra-hastic-5cd86fdccd-lqrwz hastics

Hi @spliakos, looks like you're on the right track.

Next steps to make it work:

• select one of the supported datasources (not Hastic datasource) in the Query tab on the left
• run a query so that you see a metric on the graph
• try to create an analytic unit once more

According to the specified configuration and logs, it should work.

Hi @rozetko,
Unfortunately I didn't manage to make it work. I get this persistent "Error while saving analytic Unit. Datasource is not set. If it's Grafana-test-datasource then it's not supported" as you can see in the updated screenshot I have attached.

According to issue https://github.com/hastic/hastic-grafana-app/issues/445, Hastic doesn't work in Grafana 7.2.x+, we need to look into it
