Classic problem using gz_ros_bridge

[Vaderplayz]

UBUNTU 22.04

GZ SIM 8.9.0

PX4

Hi everyone,

Im facing a problem when trying to get the camera feed from gazebo similation of PX4 SITL to ros2 for apriltag detection. Everything work nicely on GZ but when I activate the bridge, the topic does popup in the topic list of ros2 but there seems to be no output or input of any kind. ros2 topic echo or hz gain no respond, the topic still exist though with 1 pub and 1 sub which are both the bridge.
I also tried the older version which is ros_ign_bridge and I am out of idea at this point. There seems to be no valid answer on previous topic of this problem so I am making a new one with hope that someone will have a real solution.

Thankyou.

okay the problem was me using harmonic but install the default package for humble which only work for fortress. so the best solution i think would be install the correct packages from Installing Gazebo with ROS — Gazebo ionic documentation
