When I run rollout.py script, I get ‘CameraFrontRGB’ not found error. Full log is below. Any ideas how to fix this?

Hey, I was facing the same error for the past couple of days (didn’t face it before). When I changed the name of the camera to SimCamera90Front, it worked. The vehicle sensor settings menu in the simulator shows these names - “SimCamera90Front” for “CameraFrontRGB” and “Oxts” for “ImuxOxtsSensor”. Making these corrections in the config file in l2r_starter_code made it work (Probably a bug in naming sensors).
