When does this happen?

IF HuggingFaceEndpoint raises a validation error 'Could not authenticate with huggingface_hub' when used with a self-hosted model without an API token.

How others solved it

THEN Provide a HuggingFace API token either by passing the `huggingfacehub_api_token` parameter to the HuggingFaceEndpoint constructor or by setting the `HUGGINGFACEHUB_API_TOKEN` environment variable. Note that a later fix (PR #22365) removed this requirement for self-hosted models; if using an older version, this workaround is necessary.

llm = HuggingFaceEndpoint(endpoint_url=os.environ['TGI_API_URL'], huggingfacehub_api_token='hf_...')
