Hi everyone!
I am running palm, and experiencing an error when attempting to view all responses submitted through ORA. In fact, it is the exact same issue as in the post ORA grading returns error - Development - Open edX discussions. I see no issues in my server logs, but there is an error in the browser console.
I understand that this seems to be an issue with palm, and that upgrading the Open edX instance should solve this error. However, this error just suddenly appeared, without us changing any setup. Does anyone have any suggestions on how to solve this without upgrading to a newer Open edX version? Or is upgrading the only/best way to solve this?
