Rviz2 doesn't show point cloud because of wrong tf

edit

Hello everyone, I am using ROS2 Foxy on Ubuntu 20.04 and I have a pan/tilt camera which publishes a point cloud I'd like to see on Rviz2.

https://github.com/ros/robot_state_pu...

As you can see in the previous pdf, there is a correct path from odom_frame (which I select on Rviz as Fixed Frame) to tilt_link, where chassis -> pan_link and pan_link -> tilt_link are normal tf, while all the other transformations are static.

When I add the point cloud on Rviz I have this message printed on terminal:

"[rviz]: Message Filter dropping message: frame 'tilt_link' at time 641.986 for reason 'Unknown'"

and it's like if Rviz can't find a proper transformation between those two frames. Instead everything works correctly if I use only static transformations, so it's like if Rviz doesn't like "dynamic" tfs.

What does it depend on?

Thank you very much for your help.
