Running

I'm posting here because I've been blocked from receiving my course certificates for both the Agents Course and the MCP Course due to a platform-side bug that has been persisting since November 2025 — over 5 months now.

The Bug:

Every time the code checker evaluates my final quiz submission, it throws the following error:

Error checking code: 410 Client Error: Gone for url:
https://api-inference.huggingface.co/models/Qwen/Qwen2.5-Coder-32B-Instruct/v1/chat/completions
https://api-inference.huggingface.co is no longer supported.
Please use https://router.huggingface.co instead.

The checker is still calling the deprecated api-inference.huggingface.co endpoint on the backend. The error message itself confirms this is a platform issue — not a problem with my code.

The Impact:

• My final quiz shows 0 marks despite my code being correct and running successfully
• This has happened on both the Agents Course and MCP Course final quizzes
• I have been waiting since November 2025 for a fix that never came
• I am currently applying for internships and these certifications are the official proof of the work I've done. Without them, I have nothing to back my projects with when applying

What I'm requesting:

1. A fix to update the course checker to use router.huggingface.co instead of the deprecated endpoint
2. Manual review of my submissions for both courses
3. Issuance of the certificates I have earned — the only reason I don't have them is this infrastructure bug

I have screenshots of my correct code and the 410 error ready to share. I am not asking for anything I haven't earned — I just need someone to unblock this.

Is anyone else facing this same issue? Would love to know if this is affecting other students too.

Thank you 🙏
