Nvblox_examples_bringup isnt working

Im using on a Jetson Orin Nx and a Zed2i camera
I used

git clone -b release-3.1 https://github.com/NVIDIA-ISAAC-ROS/isaac_ros_common.git isaac_ros_common

When i run the NVBlox Zed example from Nvidia Github Wiki nothing works in rviz.
Launch command
ros2 launch nvblox_examples_bringup zed_example.launch.py camera:=zed2

The rviz can see the topics and i can select them but nothing shows. It wont even show a camera. when i list the topics in a terminal, I see the zed and nvblox topics are there.
The terminal prints the same 3 messages

[nvblox_node]: Lookup transform failed for frame zed_camera_link. Layer pointclouds not published
[nvblox_node]: Lookup transform failed for frame zed_camera_link. Mesh not published
[nvblox_node]: Tried to clear map outside of radius but couldn’t look up frame: zed_camera_link

To test things out i also ran the Visual Slam
When i run isaac_ros_visual_slam things work mostly fine.
I do get these messages. but not important

[visual_slam_node]: Delta between current and previous frame [399.927000 ms] is above threshold [34.000000 ms]
[rviz]: Message Filter dropping message: frame ‘odom’ at time 1729037777.728 for reason ‘discarding message because the queue is full’

Hi @Smokemonkey
please contact NVIDIA’s developers to help you with their ISAAC ROS software:

i will do that.
I thought my problem may be that the i have to set the camera to camera:=zed2
is there any functional difference between the zed2i and the zed2?

No, they are normally similar
