[OPEN] New Quizzes created by migrating Classic Quizzes cannot be edited via New Quizzes API


Engineers are currently investigating the issue.


When a New Quiz is created by migrating a Classic Quiz, the New Quiz cannot be edited using the Update a single quiz New Quizzes API endpoint (PATCH /api/quiz/v1/courses/:course_id/quizzes/:assignment_id). Attempting to do so gives a 502 status response with {"message":"Bad Gateway"} as the body of the response.

Expected Behavior

Instead users should be able to edit migrated quizzes using the New Quizzes API.



No workaround exists at this time.

Steps to Reproduce

Prerequisites: A course with a Classic Quiz.

  1. Migrate the Classic Quiz to New Quizzes (kebab menu for quiz in Quizzes index > Migrate).

  2. Attempt to make a change to the quiz using the Update a single quiz endpoint (PATCH /api/quiz/v1/courses/:course_id/quizzes/:assignment_id).

  3. Note that the quiz is not updated and the request receives a 502 status response.
