RViz did not display any points.

[hao7203]

After executing the command "roslaunch livox_ros_driver2 rviz_MID360.launch", the terminal displays the error message "Storage point data failed, can not get index", and RViz shows the error "Fixed Frame [livox_frame] does not exist". I am sure that I have changed my computer's IP address and the MID360 configuration, but the issue still persists. Has anyone encountered the same problem and could provide assistance in resolving it?
I'm using Ubuntu 18.04 and ROS Melodic.
These are the screens after I executed the command

I meet the same problem, Have you solved it？

Yes, I checked the computer using a channel and found that the LiDAR IP address did not match what the user manual stated. So, I changed the LiDAR IP to what I found, and it works.

Thank you! I did what you said.
