Thanks for reporting.

This would do it:-

teachcode/src/utils/github.js

Line 95 in ea1b46f

const API_URL = `https://api.github.com/user/repos?access_token=${userToken}`;

  const API_URL = `https://api.github.com/user/repos`;
  axios.defaults.headers.common['Authorization'] = `token ${userToken}`;

Feel free to shoot a PR.
