LAMBDAPROMPT_BACKEND = StarCoder causes runtime ValidationError on .sketch.ask

[gilgamesh7]

Hello,

I am using these in .env and load_dotenv() to load these into the runtime

LAMBDAPROMPT_BACKEND=StarCoder
SKETCH_USE_REMOTE_LAMBDAPROMPT='False'
HF_ACCESS_TOKEN=(my token)

This results in the below ValidationError.
This does work when I do not use the local copy.

Any ideas ?

Thank you !

Python 3.10.0
sketch==0.5.2
