considering it's a generated edge based on edges being added, difficult to know how to address it.

ForeignKeyEdge.ErrorMessage could be helpful but would also need to change how addEdge works in edge.go

also ^ only addresses common conflicts with edges. if there's conflicts with fields, custom graphql objects etc, not clear how that works
