Hello. I am going through this exception while trying to use a Master-detail screen for an entity that has a parent-child relationship with itself.
If I remember well, I´ve seen in this forum that it is probably related to lazy loading of reflexive relationships and I tried changing this on the entity with no positive results. I also tried adding a property for the parent in the relationship fetch plan but again, with no success.
Here is the entity:
