Quiz logs have suddenly disappeared

Question

Hello,

A few days ago I was accessing my quiz logs without an issue.  For the past few days, though, suddenly the quiz logs are blank — see screenshot.

My institution is looking into this but it's rather time sensitive that I have access to these logs again, so I'm posting here just in case anyone else has experienced this and might know a fix/workaround.

I've tried different browsers, incognito windows, all the usual but nothing has made any difference.  Toggling the "View HTML" button to "Plain Text" doesn't make a difference either.

Thank you!

Thanks Jason — I hadn't gotten as far as looking at the page source files.  But I'm glad it isn't only me experiencing this!

However, in case it's applicable in your situation, my department IT admin was able to access the logs (as an admin) and export the ones I needed into a Word doc.

A workaround for now but hopefully this issue gets resolved in the near future.

I've also been having this issue, and I first noticed it a few days ago. Today, I spent some time digging around and troubleshooting. I haven't yet found a fully satisfactory fix, but here are some findings.

I have also tried different browsers (Firefox, Chrome, Edge), incognito/private browsing modes, disabling all browser extensions, and clearing cache/cookies/browsing data for Canvas. No changes.

Inspecting (F12) the Log page for a specific question (like the image of the webpage that OP posted) and going to the Network tab reveals no error codes, indicating data packages are correctly being sent. I can even find some (but not all?) of the edit progression data by finding the "File" entries labeled "events?attempt=1&<pagination info>". If you click on one of those and go to the "Response" tab of the new sub-panel that appears, it provides a JSON file with which you can explore the file structure. You can expand a "question_answered" item and go to "event_data" and see the student's response. But not all of the Log data appears to be present - a few of the remaining questions on the assignment I'm grading didn't seem to have had their edit progression data sent over. I wonder if this partial data transfer causes the front-end UI to hang and not display the plain text nor HTML? But what's also weird is that the page will still occasionally successfully ping the Canvas servers, so there's still a response but it just… ignores the rest of the Log data that was supposed to be sent?

I noticed that Canvas recently updated some of the SpeedGrader UI elements. My issues with the Quiz Log seem to coincide with the roll out of this new update.

Hopefully someone can provide some more guidance or insight soon!
