Cannot load URDF file

[LZHLilE]

Hi, I'm using your dokcer image to create a container and steup the habitat-lab and hab-mobile-manipulation. And everything is ready, including data and episodes. However, there comes an issue about the URDF file when I tried to run a play-demo.

I'd appreciate it if you could help me.

I'm using a headless remote server. Is there any problem with the headless mode?

Sorry for the late reply. I think the error is caused from some missing asset:
