Hi, I'm developing elevation mapping based on python - ros2.

Currently, when i check the topic echo /elevation_map (custom), it is publishing correctly, but when i try to visualize it in rviz2, i am getting core_dump issue when i check the elevation_map.

I would be grateful if you could fix the error.
