Why genetated the question of “”Make sure file exists in package path and permission is set to executable (chmod +x)"

You can modify the 370 row "ros::init(argc, argv, "traj_server") " to ""ros::init(argc, argv, "poly_traj_server")" in the cpp source file of src/uav_simulator/Utils/poly_traj_server/src/traj_server.cpp, but I haven't tried yet.
