Camera prim not global?

[amirhnourian]

Hi, I am trying to enable the camera in the Leatherback Isaaclab tutorials, but I constantly get this error:

    raise ValueError(f"Prim path '{prim_path}' is not global. It must start with '/'.")
ValueError: Prim path '{ENV_REGEX_NS}/Leatherback/Rigid_Bodies/Chassis/Camera_Right' is not global. It must start with '/'.

Do you know how I can resolve this error? Here my config class:

@configclass
class LeatherbackEnvCfg(DirectRLEnvCfg):
    decimation = 4
    episode_length_s = 20.0
    action_space = 2
    observation_space = 8
    state_space = 0
    sim: SimulationCfg = SimulationCfg(dt=1 / 60, render_interval=decimation)
    robot_cfg: ArticulationCfg = LEATHERBACK_CFG.replace(prim_path="/World/envs/env_.*/Robot")
    waypoint_cfg = WAYPOINT_CFG

    throttle_dof_name = [
        "Wheel__Knuckle__Front_Left",
        "Wheel__Knuckle__Front_Right",
        "Wheel__Upright__Rear_Right",
        "Wheel__Upright__Rear_Left"
    ]
    steering_dof_name = [
        "Knuckle__Upright__Front_Right",
        "Knuckle__Upright__Front_Left",
    ]

    camera_cfg: CameraCfg = CameraCfg(
        prim_path="{ENV_REGEX_NS}/Leatherback/Rigid_Bodies/Chassis/Camera_Right",
        update_period=0.1,
        width=640,
        height=480,
        data_types=["rgb", "distance_to_image_plane"],
        spawn=sim_utils.PinholeCameraCfg(
            focal_length=24.0,
            focus_distance=400.0,
            horizontal_aperture=20.955,
            clipping_range=(0.1, 1e5),
        ),
    )

if i am not mistaken direct environments does not support {ENV_REGEX_NS}. you should use /World/envs/env_.*/
