Raised when a spatial operation combines geometries of different coordinate
dimensions (2D vs 3D) ā e.g. a 3D %Geo.PointZ{} against a 2D attribute, or
vice versa. Neo4j silently returns null for mixed-CRS operations (which then
drops rows in a WHERE), so AshNeo4j refuses up front (#270).
Bridge worlds explicitly with a downward projection
(AshNeo4j.Geo.force_2d/1) ā collapse the 3D operand to its 2D footprint
and evaluate in 2D. There is no implicit 2Dā3D lift (a height cannot be
fabricated).
