It appears that this change happened with some of the new copy-paste work that is coming in, but I can’t confirm that. The timing just seems to work out if I look at the recent commits. (I’m observing the error on edx.org, and not yet Palm, so I don’t have access to the logs)
Part of me is just hopeful that there will be a fix for this. I use this block quite a bit.
The other part wonders what the best protocol is for reporting this kind of issue. Is it raising an issue on the edx-platform repo? The x-block repo? something else
Tagging @braden since it seems like he’s involved in both the xblock and the new copy-paste work!
Thanks for the report. I will look into it. In general, to report XBlock bugs, you can open an issue on the XBlock’s repo like GitHub - open-craft/problem-builder: An XBlock for posing questions to students . Though it does sound like this may be a platform change that’s affecting problem-builder, as problem-builder is one of the only XBlocks that uses a hierarchy of blocks (XBlocks inside other XBlocks). So posting on Slack or the forum is fine if you’re not sure where the problem lies exactly.
