Deleting a github classroom assignment gets a 406 error, as of 2024/08/13

Hi everyone,

I'm trying to clean up after Spring semester, removing old github-classroom-created student repositories. Starting yesterday (Tuesday 8/13) evening, trying to delete an assignment gets a 406 error.

Steps:

1. Click the trash icon

2. Indicate that I understand the problems:

3. Then type the name of the assignment

4. The following error pops up:

This only started happening yesterday evening. I deleted several assignments earlier (waiting 10 minutes between each deletion because otherwise it doesn't finish deleting the repos) and then I started getting 406 every time. I waited until the next day, in case some rate-limiting factor were happening, but it continued to fail today too.

Update: The same bad behavior is still happening as of today (2024/08/16)

Coming from another instructor - I am noticing that the assignment copying/forking repo process is different this year. Last year, it would directly fork from the template repository, but now, it creates an intermediate template which it forks from.

I got this error when I deleted this intermediate template (attempting to verify that my code/autograding worked somewhat as expected), and then tried to delete the assignment.

The fix which just worked for me was to rename the assignment (I turned L00 into L00_deprecated, for instance), and then attempt deleting that.

Yes! That worked -- in fact I don't need to change the assignment at all: just select "Edit" and then "Update Assignment" and then the assignment can be deleted. (And it deleted the 100+ repos that had been created using it.)
