Can't require column hostgroup_name in model

[picoroma (PiCo)]

I have this error if I try to create a report like this:

My Module version:

[moreamazingnick]

for the icingadb reports the syntax/fields are a little different.
I recommend to build the query in the webgui and then copy and past it. maybe revert the url encoding:
try out this:

hostgroup.name=BGB_LAB
