Using LMS course copy breaks assignments: steps to reproduce

[mkdir-washington-edu]

Describe the bug When instructors copy a course in Canvas students can run into an authorization loop. This is possibly intermittent, but we've been able to reproduce it consistently in assignments using Canvas Files.

To Reproduce See comment below.

Expected behavior In Canvas: Instructors expect to copy a course, have students authorize once, and have them access the assignment. In other LMSs: Instructors expect to copy a course and for assignments to "just work" in the new course.

Steps to reproduce the behavior in Canvas:

1. Log-ins for Canvas instructors and students are here: https://docs.google.com/document/d/1Nl-ytl92Ydg-Z-1oQjUQUW_tt_AIVxXctrYXMD1Eqzs/edit
2. Create an Assignment in a Canvas Course using a PDF Canvas Files - https://web.hypothes.is/help/using-the-hypothesis-app-with-assignments-in-canvas/
3. In the course's left hand menu, click "Settings"
4. In the right hand menu click "Copy this Course"
5. Click "Create Course"
6. In the new course, in the left hand menu, click Settings
7. Publish the Course
8. In the new course, in the left hand menu, click "People"
9. Click "+People" and add a student to the new Course. Make sure this student is ONLY in the new course. If the student is enrolled in the "old" course, the assignments in the new course will work.
10. Log in as that student
11. Enter the new course and go to "Assignments"
12. Click on the Canvas Files assignment
13. Attempt to authorize Hypothesis. Experience the loop.

To quickly experience the problem:

1. Log in as student 1, 2, or 3
2. Enter the course "Support 103c - adjust"
3. In Assignments, click on "Canvas Files PDF"

I wonder if what is happening is that Canvas files have different IDs in the original and copied courses and so the Canvas file ID in the URL used for the assignment is no longer correct after the copy. If this was the issue, then the assignment would probably work for teachers who are members of the original and the copied course but not for students who are members only of the copied (new) course.

If this is the problem we might be able to switch to identifying files by file path or name instead - assuming those are preserved.

Steps to reproduce in Blackboard:

[teacher and student logins available in 1Password]

1. Create a course with at least 1 Hypothesis-enabled reading
2. Follow these instructions to copy the contents of that course to a new course (
3. Access the course site as a teacher - you'll note that the links to the Hypothesis-enabled readings are broken

Steps to reproduce in Moodle:

[teacher and student logins available in 1Password]

1. Create or enter a course with at least 1 Hypothesis-enabled reading
2. In the left navigation menu, go to Site Administration > Courses > Manage courses and categories
3. Find the course you wish to copy under the "Miscellaneous" heading
4. Next to the course title, click on the Duplicate icon (next to the cog; looks like 2 sheets of paper)
5. Name your new course and click "copy and view"
6. Once the copying process is complete, go to your new course
7. Click on any Hypothesis-enabled reading in the new course. You'll see that the original content link isn't preserved - when you click on the link as a teacher, you'll be prompted to re-link a document or web page to the assignment
