[Bug]: none of the nodes are being published after launching robot_describtion.launch file

[prj281]

What happened?

I am able to launch the xslocobot_description.launch file successfully. But after launching, the nodes are not been published. I am unable to visualize the robot in rviz. A global warning appears in rviz which says "no tf data". I have attached the screen short of rviz and the terminal below

when we give the value of joint_state_pub as true , another error occurs which shows the invalid input type.

could you please help us in solving this issue.

Are you running this on the LoCoBot computer, or your own machine? Please provide the output of ros2 node list and ros2 topic list.

GoodEvening Sir, I hope this mail finds you well. Currently, I am working with locobot_wx250s. I have downloaded all the packages of ros2 galactic version successfully. I have given all the parameters required to launch the description.launch file. but when i give the joint_state_pub as true, it is throwing an error suggesting that i have used an invalid type.. but if i have used the value of joint_state_pub as false, it will launch the rviz but i am unable to visualize the robot and it shows global warning saying that "no tf data. /locobot/base_link does not exist"(pic:joint_pub_false.png). none of the nodes are getting published(pic:node_list.png). When I give the joint_pub as true, it throws an error(pic: joint_pub_true.png). All these might be because of my mistake.I kindly request you to help me figure out this issue so that we can complete our work as much as possible. Please Sir with regards, Alka P
