Additional context
This might be a global PopCode issue, which means the Unit 9 project where students export to Github might be stalled if it is not fixed.

Beginne damit, den Export Repo-Ablauf zu reproduzieren: Melde dich mit einem verknüpften GitHub-Konto an, wähle Export Repo und untersuche die POST-Anfrage an https://api.github.com/user/repos. Verfolge die für diese Anfrage verwendeten Anmeldedaten des verknüpften Kontos und überprüfe, dass der abgeschlossene Ablauf das Repository erstellt und den Benutzer zu GitHub weiterleitet.
