> I am attempting to model parent child relationships with the V2 Entity API.
> I define a type that has
> - a single optional parent attribute of our type.
> - a children optional List CONSTRAINT_TYPE_MAPPED_FROM_REF pointing to its
> own type and a parent attribute.
> When I create entities and try to knit them together as parent and child
> Atlas loops. I have included a test program I used to create this error.
> The console shows the loop:
