I am having trouble seeing the peer reviews for an assignment. I know that they are there as I can see some of them via the grade book in both the production environment and in the test environment. I can also see that they exist via the API. However, they are are not being shown by speed grader.

In current production Canvas environment the view from the gradebook is (Note that I have tried to white out any student's details):

Gradebook view

Note that there no sign of the peer review in the comments.

The SpeedGrader view shows:

SpeedGrader view

Again, there is no evidence of the peer review.

In contrast the test instance shows:

test instance gradebook

However, SpeedGrader view in the test instance also doesn't display the information about the peer review:

test instance speedgrader view

The solution was to write python program (list-peer_reviewing_assignments-1.py) to get the peer reviews with submission_comments:

def list_peer_review_assignments(course_id, assignment_id):
       peer_review_assignments_found_thus_far=[]

       # Use the Canvas API to get the list of peer reviewing assignments
       # a given assignment for a course:
       #GET /api/v1/courses/:course_id/assignments/:assignment_id/peer_reviews
       
       url = baseUrl + '%s/assignments/%s/peer_reviews' % (course_id, assignment_id)
       if Verbose_Flag:
              print("url: " + url)

       payload={'include[]': "submission_comments"}
       r = requests.get(url, headers = header, data=payload)
       #r = requests.get(url, headers = header)
       if Verbose_Flag:
              write_to_log("result of getting peer review assignments: " + r.text)

       if r.status_code == requests.codes.ok:
              page_response=r.json()

       for p_response in page_response:  
              peer_review_assignments_found_thus_far.append(p_response)

       # the following is needed when the response has been paginated
       # i.e., when the response is split into pieces - each returning only some of the list of modules
       # see "Handling Pagination" - Discussion created by tyler.clair@usu.edu on Apr 27, 2015, https://community.canvaslms.com/thread/1500
       if 'link' in r.headers:
              while r.links['current']['url'] != r.links['last']['url']:  
                     r = requests.get(r.links['next']['url'], headers=header)  
                     page_response = r.json()  
                     for p_response in page_response:  
                            peer_review_assignments_found_thus_far.append(p_response)

       return peer_review_assignments_found_thus_far

Then look at the submisison_comments field and extract the URLs from the 'attachments' element, of the form: https://kth.instructure.com/files/yyy/download?download_frd=1&verifier=xxx

These URLs can be accessed via a browser and saved locally for viewing.

(I have currently worked through getting and reading 116 of these out of 158!)
