I am encountering a **410 Client Error: Gone** when submitting the Unit 2.1 quiz for the AI Agents course.

**Error details:** \> The grader appears to be calling the retired endpoint: `/static-proxy?url=https%3A%2F%2Fapi-inference.huggingface.co%2Fmodels%2FQwen%2FQwen2.5-Coder-32B-Instruct%60.

**Observed Behavior:**

- The error persists even when using the official solution.

- Manual sanity checks (submitting minimal code) return the same 410 error.

It seems the “Space-side” grader needs to be updated to use `/static-proxy?url=https%3A%2F%2Frouter.huggingface.co%60. Is there a fix planned for this grader?
