Can't view NUMBAS exams

[Joshua Lim]

Hi Christian and folks! 

When we download a NUMBAS scorm from numbas.mathcentre.ac.uk it opens to the error message:

Numbas has failed
Sorry, Numbas has encountered an error which means it can't continue. Below is a description of the error.

TypeError: Cannot read properties of undefined (reading 'root') 

This happens even for exams I download them as SCORM package (and add them to Moodle via our NUMBAS LTI or a vanilla SCORM activity) and the Standalone .zip (no SCORM). This exam seems to preview fine in when I Run in the Editor, but not when I download. Is there something broken with the compile step?

I was just going to share an example exam and was going to pick a public demo and I noticed that Easy exam actually works (there is only 1 question!) but the  Numbas website demo doesn't and gives me the same issues as other exams!

Cheers,

Josh

Thanks for reporting this. I think I made a mistake in a change on Friday, and I'm working to undo it now.
