Description

Hello there, I've trying to use the spatial mapping feature with my ZED One by making a service call to ~/enable_mapping but it doesn't seem to be working.

Steps to Reproduce

Run rviz display launch file:

ros2 launch zed_display_rviz2 display_zed_cam.launch.py camera_model:=zed

Make service call to enable mapping:

ros2 service call /zed/zed_node/enable_mapping std_srvs/srv/SetBool data:\ true\

Expected Result

I expected to see the ~/fused_cloud pointcloud topic populate and show feedback in RViz

Actual Result

Instead, nothing appears in RViz, the service call responds with:

waiting for service to become available...
requester: making request: std_srvs.srv.SetBool_Request(data=True)

response:
std_srvs.srv.SetBool_Response(success=True, message='Spatial Mapping started')

and when ~/fused_cloud is echoed the data field remains empty:
