I am working with Carla, Autoware and ROS and everytime I try to run thestart_env package , I am getting this error. This package basically launches the spawn_ego_vehcile.py file. Any help would be appreciated.

Details of the workspace after running is as follows:

$ roslaunch start_autoware_env.launch ... logging to /home/automotive/.ros/log/adf98fc6-ebaa-11ec-ad00-50ebf6229861/roslaunch-automotive-18750.log Checking log directory for disk usage. This may take a while. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.
