[ROS2 Rviz Error : Global Status Warn Fixed Frame No tf data. Actual error: Frame [world] does not exist]

I got this error in Rviz.

How I solve this error?

./run_editor.sh <false or true to use dds server or not> $(pwd) <ue_exe>
cd turtlebot3-UE && source fastdds_setup.sh
ros2 launch nav2_bringup tb3_simulation_launch.py use_simulator:=False map:=<path to turtlebot3-UE>/Content/Turtlebot3_benchmark.yaml 

I did this command. OS version :ubuntu 20.04 unreal engine5.1.1

[yuokamoto]

Do you see turtlebot3 and lidar rays(red dots) in the scene?

[Buddies-as-you-know]

No,I don't see it.

[yuokamoto]

Can you share the screenshot when you Play the simulation?

[Buddies-as-you-know]

[Buddies-as-you-know]

I got a error when I Play the simulation.

I did source /opt/ros/foxy/setup.bash before starting Unreal Editor.

[yuokamoto]

Please run editor without source /opt/ros/foxy/setup.bash Since rclUE has ros2 lib inside, you should not source /opt/ros/foxy/setup.bash

[Buddies-as-you-know]

I see turtlebot3 and lidar rays(red dots) in the scene. But, I get Warm "No tf data No tf data. Actual error: Frame [world] does not exist]" I can't do 2D estimate and Naviagation2 Goal.

[controller_server-6] [INFO] [1686547054.787731326] [local_costmap.local_costmap]: Timed out waiting for transform from base_link to odom to become available, tf error: Invalid frame ID "odom" passed to canTransform argument target_frame - frame does not exist

[yuokamoto]

In your terminal which start navigation

• Please make sure that you execute cd turtlebot3-UE && source fastdds_setup.sh
• try ros2 topic echo /clock if you can see /clock topic, ros2 communication is working.

[Buddies-as-you-know]

I tryied try ros2 topic echo /clock. I got "WARNING: topic [/clock] does not appear to be published yet Could not determine the type for the passed topic".

[yuokamoto]

Then I guess, something wrong with ros2 connection. To connect to ros2 dds server, you need to execute source fastdds_setup.sh in the terminal

[Buddies-as-you-know]

I executed source fastdds_setup.sh in the terminal. But ros2 topic echo /clock accured WARNING: topic [/clock] does not appear to be published yet Could not determine the type for the passed topic. I excuteed ros2 topic list. /parameter_events /rosout I don't see /clock.

[yuokamoto]

hmm, not sure what is wrong. here is the video of I run the turtlebot3-UE sim. Could you check?

navigation has moved. thank you.
