I encounter a similar error when running the template agent: https://huggingface.co/spaces/agents-course/First_agent_template

You need to create Hugging Face access token here https://huggingface.co/settings/tokens and then add it to you space settings here https://huggingface.co/spaces/<USER_NAME>/First_agent_template/settings -> Secrets as HF_TOKEN

Probably, you need to restart you deployment, so it will be pulled to runtime

And we absolutely need to add this information to course unit
