I'm getting "Cannot read property 'message' of null" for all of my panes on https://grafana.wikimedia.org/dashboard/db/ores-labs
https://github.com/grafana/grafana/issues/4499 seems relevant. The consensus seems to be that CORS issues are likely culprit. However a quick chat in Cloud-Services identified that it's probably due to a link for the datasource getting a 302 redirect.
<bd808> graphite.wmflabs.org -> graphite-labs.wikimedia.org in https://grafana-admin.wikimedia.org/datasources
I changed the URL to point directly to graphite-labs.wikimedia.org now. Try?
I think @fgiunchedi would like us to move all labs stuff off grafana.wikimedia.org once grafana-labs.wikimedia.org is fully functional (right now only grafana-labs-admin.wikimedia.org works).
given that T143556: Setting up grafana should also setup Anonymous read-only access for the default org is essentially fixed (grafana-labs available for non-logged in users too) I went ahead and removed the graphite-labs data source from grafana.wikimedia.org
