Hey @amiryanj, have you checked the QoS? By default, subscribers use best effort. You can also change them using launch params.

Hey @mgonzs13
Thanks for your quick feedback.
I am kinda new to ROS2. I just checked out the Reliability Policies, they sound to be matching.
There is only one policy that is not matched (the Durability of the publisher on /camera/depth/image_rect_raw.
Not sure if that can be the reason? and how to fix that possibly?

Are you getting messages in the /yolo/detections topic? In the case of the 3D, you also have to set the target_frame to your base frame, for example, camera_link.
