Some relations not working

I have relations setup on my schema, most of which work. I have two relations on my appearance table - user_assigned_id and user_booking_id which relate to the profile table. When I do a get request on appearance with ‘*’ for the relations, they all come through except profile_by_user_assigned_id, even though user_assigned_id has a value, the relation is a null.

What am I doing wrong? The only difference between user_assigned_id and user_booking_id in the schema is that user_booking_id can’t be null, and user_assigned_id can be.
