ros-ign-bridge not publishing CameraInfo

edit

Hi I'm using Gazebo Fortress compiled from sources on Ubuntu 20.04 with ROS Noetic

When running roslaunch ros_ign_gazebo_demos rgbd_camera_bridge.launch

If I add a Camera view in RViz I get the warning CameraInfo not published.

Is this considered a normal behavior?

If not, how can I fix this?

EDIT: I've figured out the following: In the Gazebo GUI, add the Image Display plugin, then select the depth image. The message will then be published on the associated Gazebo topic.

My question now is: How do I get the data to be published without using the GUI?
