what is the issue exactly?

[tslgithub]

when i run the command:
ns-render camera-path --load-config outputs/poster/nerfacto/2024-04-19_201438/config.yml --camera-path-filename /home/accer2/project/people/nerfstudio/data/nerfstudio/poster/camera_paths/2024-04-19-20-14-45.json --output-path renders/poster/2024-04-19-20-14-45.mp4

and it runs:
Loading latest checkpoint from load_dir

then i meet the error:

I found is my "camera_path": []", camera_path is empty, but what "camera_path" means ???

Hi! This should be the camera path to render your video, which can be created in the viewer.
