Hello,
I am trying to write 3D Geometries (Points and Linestrings) to an Oracle-Database (21c Express). In the process all z-Coordinates get lost and SDO_GTYPE is wrongly written as 2001 or 2002 (2-Dimensional Geometries) instead of 3001 and 3002.
Multiple Geometries are entering the writer as an aggregate (example below).

Apart from the z-Coordinate missing these are written and interpreted correctly when writing to Oracle. I have checked the “Contains Z Ordinate” Option in the Writer-Parameters.
Does anyone have anymore ideas what I could try?
