[Bug Report] AttributeError when running check_mesh_subterrains.py: missing platform_height in repeated object terrain configs

[BaoyiCui]

Describe the bug

I was experimenting with mesh sub-terrains in my environment. When running the script source/isaaclab/test/terrains/check_mesh_subterrains.py, I encountered the following error:

AttributeError: 'MeshRepeatedPyramidsTerrainCfg' object has no attribute 'platform_height'. Did you mean: 'platform_width'?

It looks like every call to test_repeated_objects_terrain fails with a similar issue.

Steps to reproduce

conda activate env_isaaclab
cd IsaacLab # replace this with your isaaclab root directory
python source/isaaclab/test/terrains/check_mesh_subterrains.py

System Info

• Isaac Sim Version: 5.0
