I'm coming at my wit's end here.
I have an automation set up to look at one Asset custom field (Impacted Configuration Items), and collect in a lookup Action.
From that action, I want to view the references it has and update a second Asset custom field (Affected Service Offering(s)).

I set up a Log Action to verify it's picking up the correct objects.

But it fails, giving me the following error:

Where am I going wrong?
