I don't know why I can't find joint_state_publisher in noetic

Hi I'm using ubuntu 20.04 & noetic & windows 10

This is my launch file

$ roslaunch testbot_description testbot.launch $ rviz

Rviz is working(I can see manipulator). But jointstatepublisher window is missing. So I can't control my manipulator..

Thank you for your help

This is urdf <?xml version="1.0" ?>

NODES / jointstatepublisher (jointstatepublisher/jointstatepublisher) robotstatepublisher (robotstatepublisher/robotstatepublisher)

process[jointstatepublisher-1]: started with pid [47969] process[robotstatepublisher-2]: started with pid [47970]
