Is this for a specific lab? A link would be helpful here.

Add this to your LiteLLM Proxy config.yaml file: /root/config/config.yaml

litellm_settings:
  drop_params: true  # Drops unsupported params globally [page:1]

Stop litellm proxy
pkill -f "litellm --config"

reinitialize
source /root/venv/bin/activate && python3 /root/code/verify_environment.py

and it works

Well done, @ aimhwak! I’ve tried your fix in the lab, and it works indeed. I’ve passed it on to our engineers to repair the lab.
