Hi, I am working on iterative summarisation of long documents using Qwen/Qwen2.5-14B-Instruct-1M via langchain’s HuggingFaceEndpoint. Despite using an access token from a Pro account to login, I get the following error: Error processing batch 1: 402, message=‘Payment Required’, url=‘[https://router.huggingface.co/featherless-ai/v1/chat/completions](https://router.huggingface.co/featherless-ai/v1/chat/completions)’ The link shows the following: {“error”:“Invalid username or password.”} which is confusing based on the error message. Has anyone encountered similar? ---

Hey Fyahdii! That 402 error with the “Invalid username or password” message is odd, especially with a Pro account. I’ve hit similar issues with Hugging Face’s API when the token wasn’t set up right. Check that your `HUGGINGFACEHUB_API_TOKEN` is correctly loaded in your environment (e.g., via `os.environ` or `.env`) and matches the token from your Hugging Face account settings—copy-paste can sometimes add hidden characters. Also, verify the `repo_id` for `Qwen/Qwen2.5-14B-Instruct-1M` is correct, as a mismatch can cause errors. Could you share a snippet of how you’re initializing `HuggingFaceEndpoint`? Has anyone else seen 402 errors with Qwen models on LangChain? ---

Thank you for responding and for your help. I think I have been able to resolve this by generating a new token and using that one instead. ---

Nevermind the error came back again ---

It seems that this may also occur due to permission settings on Hugging Face’s side? > [@402 Client Error: Payment Required for url: https://router.huggingface.co/hf-inference/models/meta-llama/Llama-3.3-70B-Instruct/v1/chat/completions (Request ID: Root=1-67e420cf-1ec0ac2a3a3102965c52fe0f;8fe0d876-5406-4953-9fd4-e7b03cd17bb5)](https://discuss.huggingface.co/t/402-client-error-payment-required-for-url-https-router-huggingface-co-hf-inference-models-meta-llama-llama-3-3-70b-instruct-v1-chat-completions-request-id-root-1-67e420cf-1ec0ac2a3a3102965c52fe0f-8fe0d876-5406-4953-9fd4-e7b03cd17bb5/148414/3): > > Hi @TUSTResearcher Typically, this error message occurs if there isn’t a payment method on your account or your access token doesn’t have the right permissions.

Thanks for your help. Based on the linked post, the token I am using appears to have the correct permissions, and there is a payment method with an active subscription on the account, so I suspect it’s most likely something else. Do you know how I might check the permission settings? ---

Hmm… I don’t know how to check that on the user side… It may be quicker to contact Hugging Face. @meganariley [billing@huggingface.co](mailto:billing@huggingface.co) ---
