Why are instructions and quiz_settings null in the New Quizzes API?

[GabrieleMaurina]

I make requests to this endpoint:
GET /api/quiz/v1/courses/:course_id/quizzes

In the list I get back, sometimes instructions and quiz_settings are null. Why? How do I prevent this?

Here is an example where quiz #3 does not have instructions nor settings:

You should do the same. In the event you use an IDE or access the web, be aware that may cause your work to be affected by an LLM, which will trigger an academic misconduct penalty.</p>",
