How to complete the challenge GET /challenger/guid (200)
This challenge applies when challenger persistence is enabled. Use the saved challenger GUID in the URL so the server can restore that challenger's progress from persistence into memory.
The request path is /challenger/{guid}. Replace {guid} with the saved challenger id.
For active sessions, the same endpoint also returns challenger progress data. For this persistence challenge, the important behaviour is that the challenger id can be restored and the response status is 200.
