@daud99 there's a test failing. Could you inspect and update here?

[daud99]

@DhanshreeA Okay I'm checking it.

The test failure is happening because we've hit GitHub's hourly API request limit. The code is fine - we just need to wait for the rate limit to reset and run the test again.

The error shows this clearly:

403 Client Error: rate limit exceeded for url: https://api.github.com/users/ersilia-os/repos
