ros2 topic echo /tf and ros2 topic echo /odom yield blank #1514

I am learning ROS2 and Gazebo. I am using Humble and Gazebo classic 11. I tried running the differential drive example code but it does not resolve the tf in RVIZ. I also tried ros2 topic echo with /tf and /odom which just return blank. What could be the issue? I made sure all the link names are correct and all indentations and tags are closed. `<?xml version="1.0"?>
