I get the following error:
$ ros2 launch clearpath_gz simulation.launch.py

[INFO] [launch]: All log files can be found below /home/user/.ros/log/2026-07-18-20-21-33-178926-4_xterm-4803
[INFO] [launch]: Default logging verbosity is set to INFO
[ERROR] [launch]: Caught exception in launch (see debug for traceback): Hostname 4_xterm cannot contain characters other than [A-Z][a-z][0-9] and -

Any solutions?
