Description Andrew Pickering 2022-04-07 02:12:42 UTC 
The Observe > Dashboards page doesn't handle the `$__range`, `$__range_s` or `$__range_ms` variables. This causes the Thanos API to return an error if any dashboard panel uses one of these variables.
Comment 3 Junqi Zhao 2022-04-18 06:53:26 UTC 
tested with 4.11.0-0.nightly-2022-04-16-163450 and used the attached dashboard file, create configmap under openshift-config-managed, dashboard name: testing

*******************
go to "Observe -> Dashboards", choose dashboard testing, select any value from "Time Range" drop-down list, for example "Last 15 minutes", "HTTP Request Total" section, click Inspect, prometheus expr is: (topk(5, sum(rate(http_requests_total[900s])) by (instance)))
$__range is parsed right, 15*60=900s
