TypeError: can only concatenate str (not "ListConfig") to str

Hi, thanks for your awesome work. The commands for kitchen environment run well and training results are also reasonable. However, the command of Adroit pen task fails to run in my case.

The versions of the relevant packages are as follows:

hydra-core==1.1.1
hydra-submitit-launcher==1.1.5
omegaconf==2.1.1

They are the same as in your r3m_base.yaml. I also have tried other versions, but the bug is always there. Do you have any suggestions?
