this.metricFindQuery(...) is undefined error

#1

I am getting following error:

Templating init failed
this.metricFindQuery(...) is undefined

randomly on every page in Grafana Kubernetes App. Then it disappears. Moreover all graphs are working fine. Any idea where that come from?

#2

That comes from the template variable queries. Sounds like maybe a bug. Are the template variable dropdowns working correctly?

#3

Yes, dropdown menus are working fine. Where I should look for that, is it in dashboard json files or somewhere else?
