The code provided in the course using the Qwen model build and runs fine, there are no log errors either. However when i attempt to chat with agent it never responds. The only advice given was to change the model…which I did but still no answer. Really want to proceed with the course but i cant till i can get this agent responding. Any help would be appreciated. Thank you ---

can you share your space if it’s public? ---

**Hi @12GaugeMage,** I’m also facing the same issue. Based on your agent’s weblink [here](https://huggingface.co/spaces/12GaugeMage/First_agent_template), I checked the logs (you can view them by clicking the “Logs” button on the webpage where your space is running). The logs indicate the following error: ```auto Error in generating model output: 401 Client Error: Unauthorized for url: https://router.huggingface.co/hf-inference/models/Qwen/Qwen2.5-Coder-32B-Instruc t/v1/chat/completions (Request ID: Root=1-67c03071-27d09e05777ee5be59165163;7c1a7376-6f61-4430-8dc4-e93100cb7646) Invalid username or password. ``` This suggests an authentication issue when trying to access the Hugging Face inference API for the Qwen model. Additionally, the traceback error at: ```auto total_input_tokens += agent.model.last_input_token_count TypeError: unsupported operand type(s) for +=: 'int' and 'NoneType' ``` indicates that `last_input_token_count` might be returning `None`, which is causing the agent to fail. I noticed that a commit has already been made addressing this issue [here](https://huggingface.co/spaces/agents-course/First_agent_template/commit/ae7a4944c6d5660f2caab0c947c20c3d1059b749). To resolve the problem, try updating the `model_id` in your code as follows: ```python model_id = 'https://pflgm2locj2t89co.us-east-1.aws.endpoints.huggingface.cloud' ``` This should fix the issue and allow your agent to respond. Let me know if you need any further help! ---
