Omniverse Isaac Sim

I am trying this tutorial: Isaac Sim: Generating Synthetic Data using Replicator Composer - YouTube

After write my tutorial.yamlconfigurarion as following:

# object parameters
flying_objects:
  obj_model: Choice(["/home/henry/Projects/omniverse/isaac-sim/composer-workspace/assets/models/warehouse.txt", "/home/henry/Projects/omniverse/isaac-sim/composer-workspace/assets/models/office.txt", "/home/henry/Projects/omniverse/isaac-sim/composer-workspace/assets/models/hospital.txt"])
  obj_material: Choice(["/home/henry/Projects/omniverse/isaac-sim/composer-workspace/assets/materials/materials.txt"])

  obj_count: Range(15, 30)
  obj_size: Uniform(25, 100)

  obj_rot: Uniform((0, 0, 0), (360, 360, 360))

  obj_horiz_fov_loc: Uniform(-1, 1)
  obj_vert_fov_loc: Uniform(-1, 1)
  obj_distance: Uniform(400, 1000)

# light parameters
camera_light:
  light_color: Uniform((0, 0, 0), (255, 255, 255))
  light_count: 1
  light_intensity: 100000
  light_radius: 50
  light_distance: 50

flying_lights:
  light_count: Range(1, 3)

  light_color: Uniform((0, 0, 0), (255, 255, 255))
  light_intensity: Uniform(0, 1000000)
  light_radius: 20
  light_distance: Uniform(400, 800)

# room parameters
scenario_room_enabled: True

floor_size: 2000
wall_height: 2000

#floor_material: Choice(["/home/henry/Projects/omniverse/isaac-sim/composer-workspace/assets/materials/materials.txt"])
#wall_materials: Choice(["/home/henry/Projects/omniverse/isaac-sim/composer-workspace/assets/materials/materials.txt"])


# camera parameters
camera_coord: Uniform((-500, -500, 30), (500, 500, 200))
camera_rot: Normal((0, 0, 0), (25, 25, 25))

I am getting the following error:

The issue might occur because the video tutorial is using an older API, you can use that to get a better understanding, however the best would be to use the documentation and tutorials for the latest API.

If the issue still persist can you share a step by step setup to reproduce the error?
