Issue with Get all quiz submission questions When "One Question at a Time" is Enabled

[brandon42]

Hello Canvas Community,

I’m experiencing an issue with the Canvas LMS API when retrieving quiz submission questions. Normally, the API request to: 

GET /api/v1/quiz_submissions/:quiz_submission_id/questions

works correctly and returns the submission questions. However, once the quiz is set to "One Question at a Time", the API response changes to:

Response : 

{ "status": "unauthorized", "message": "Cannot receive one question at a time questions in the API" }

I couldn't replicate it.

On a quiz where I had "one question at a time" enabled, I used /api/v1/courses/:course_id/quizzes/:quiz_id/submissions to pick the first id of a submission, and then used /api/v1/quiz_submissions/:quiz_submission_id/questions, and it worked.

I also tried on another quiz for which students submitted their answers while the option was not enabled, and then I enabled it. I can still see that submission in the API.
