[mariusz-gomse-centra]

1. Create Dashboard object
2. In configJson put json with ${env} (which is datasource from variable) - this json was generated by grafana

3. apply to k8s

You'll get an error like below and dashboard won't be synced:

 Warning  CannotObserveExternalResource  2m38s (x21 over 17m)  managed/oss.grafana.crossplane.io/v1alpha1, kind=dashboard  cannot run refresh: refresh failed: Invalid reference: A reference to a resource type must be followed by at least one attribute access, specifying the resource name.
Invalid reference: A reference to a resource type must be followed by at least one attribute access, specifying the resource name.

If you change in configJson ${env} to something then everything is OK (but you won't have dynamic datasource in panel)

I'm closing this because after creation I found out that there is other issue for it: https://github.com/grafana/crossplane-provider-grafana/issues/59 (and solution is also there)
