422 error on Quiz submission post.

[jnwilson]

Sorry for what may be just a typical newb question.
I'm trying to write a python script to upload quiz scores.
It yields a 422 error.
I can do a get on the same URL, so the quiz submission being modified actually exists.

An appropriately sanitized curl version of the request is the following:

curl  https://mysite.com/api/v1/courses/#######/quizzes/######/submissions/######## \
     -d '{"quiz_submissions" : [{"attempt": 2, "fudge_points": 0, "questions": {"1": {"score": 7.0, "comment": "Category,Pts,Deductions;Report Clarity,1.0,1.0;Key 1,1.0,;Key 1 method,2.0,2.0;Key 2,1.0,;Key 2 method,2.0,;,,;Score,,7.0"}}}]}' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer <MyTokenValueHere>'

The text of the response includes this message (which seems to be less than accurate or relevant):

There was a problem with your last request.  You may have tried to perform an action after a long period of inactivity.  If that&#39;s the case, try going back, reloading the page you were working on, and resubmitting.  If not, please let us know what you were doing when the error happened.

If you see an obvious problem, I will sing the praises of your name.

And, yes, I am the teacher of the class, using one of my access tokens.

BTW, I found a doc that said the score must be an integer. I changed it to 7 from 7.0 and it still yields a 422 error.

And now I found that the question id is actually a 6-digit ids and not an ordinal. I think this is the key. I must test it.

And it's still broken, even with a valid question id

I was doing a POST rather than PUT. PUT worked fine.
