Isaac Lab Multi-Agent skrl documentation not working

[Saumya-Karan]

I tried running MAPPO to train the multi-agent environment Isaac-Shadow-Hand-Over-Direct-v0 with skrl using the following command:
isaaclab.bat -p source\standalone\workflows\skrl\train.py --task Isaac-Shadow-Hand-Over-Direct-v0 --headless --algorithm MAPPO

I am getting the following error:
Error executing job with overrides:
