The selectors used do not exist on GHE 2.20. I've never had need for the functionality, so never cared, but noticed it is throwing an exception today.

Upgrading to 2.21 is on the docket for "soon", maybe the markup will finally be updated. Otherwise opening for awareness and I'll address it when I get a chance.
Can you see what the selector is?

@busches please check this tomorrow when the next released is out. We changed the way it works and you should not get an error.
@busches is this still an issue?
@yakov116 probably. I will hopefully get some time to look into everything enterprise in the coming weeks.
FYI, saw this was working today.
