Yeah, we want to make this, and other errors, easier to debug. Not sure when we’ll work on it.

It’s actually quite hard to do performantly, since [it would imply a potentially unlimited search through the relationship tree](https://community.fibery.io/t/recursive-groupby-in-lists-stop-working-as-expected/6197/7).

I can’t think of a way of solving this using the existing Fibery capabilities.  
Maybe something will become possible if/when Fibery has a [union function](https://community.fibery.io/t/union-function-to-merge-multiple-collections-into-a-single-collections-field/5680) in formulas 🤔
