When creating an event definition in 6.1, and moving to the Condition tab, and selecting Filter & Aggregation as the condition type, a red "Could not execute search" box pops with no other input on the page/tab:

I can't seem to replicate this in any of our test environments that I try to do so in, so looks like it's limited to my own. I'm also going on vacation next week, so it would be after next week before I can look at it further. @dennisoelkers want to close this one for now, and I can open a new one if I can figure out how to replicate it in a system you also have access to?
