I want through this laser scan tutorial to send laser scan message in ROS. And I want to display the laser scan in Rviz. But it failed. The Status of LaserScan become error. Also I want to select fixed frame to "laser_frame", but not exist. But I run rostopic echo /Scan, I can see the frame_id in each data stream. Any suggestions, thanks for your help.

1: After adding tf informations, I can select laser_frame as Fixed Frame of Global Option. But still nothing shown in Rviz
