Generally, I would suggest that this should error out, saying "no folder specified". But, in Grafana land, perhaps it is okay to just select the General folder in this case.

WDYT? Could you make a PR?

Well it should already do it actually https://github.com/grafana/grizzly/blob/v0.2.0-beta3/pkg/grafana/dashboard-handler.go#L75.... Not sure why it doesn't, I will try to debug it this week,
