"The studio is having trouble saving your work" error

Hi everyone,

I’m currently setting up Open edX on Ubuntu 22.04 running on VMware. I installed it using Docker (Tutor + Docker Compose), and I was able to successfully launch the LMS and access the web interface.

However, I’m running into an issue when interacting with problems (e.g., selecting an answer in a quiz). After choosing an answer, I get the following error message:

“The studio is having trouble saving your work”

As a result, the answer is not saved and no feedback/result is shown.

I checked the browser console and saw multiple errors like:

  • 403 (Forbidden) on some API requests

  • Studio AJAX Error

  • Unhandled message type: VIDEO_XHR_CANDIDATE

I’m not very familiar with Ubuntu or backend configuration, so I’m not sure where the problem is coming from.

My setup:

  • Ubuntu 22.04 (on VMware)

  • Open edX via Tutor (Docker + Docker Compose)

  • Accessing LMS via browser (no HTTPS yet)

Has anyone experienced this issue before or knows what might be causing it? Any guidance would be greatly appreciated.

Thank you!

Hi! When making forums posts could you please specify which Open edX version you’re using @Vu_M_nh_Tu ? Thank you.

@sarina How can I check which Open edX version I am using?

Hi @Vu_M_nh_Tu
To check your version you can run tutor --version in the commandline.

I’m not too sure about the specific errors you are getting, however it may be useful to check the system logs:
run tutor local logs -f --tail=1 (this will start displaying logs in real-time as they are generated while ignoring older log entries)
reproduce the error/issue on the site, hopefully this event should have been captured by the logging
press CTRL+C to stop displaying new logs, then you can copy/paste the log details into a code block here for easier reading (preferred to avoid screenshots wherever possible)
before posting the logs here just make sure to sanitise any confidential information you don’t want public (names, URLs, IP addresses, etc)

With some luck there may be useful information in these logs that can aid us in troubleshooting your issue.
Hope this helps :slight_smile:
