Hi, all.
We've got an issue where grades aren't being reported back to Blackboard, even though the system says they are.
The grades definitely exist in Numbas--they've got valid receipt codes and everything--but they're not being automatically reported back to Blackboard even though they're set up to. Trying to push them manually from Numbas *seems* to work in that we don't get any error messages, but the grades never show up.
I've had a similar problem before that turned out to be an overzealous security header setting that was keeping Numbas from reading its own cookies. This time, though, I've had a look in the browser console, and everything seems to be working normally. Trying to report grades manually has the system do a GET to
https://numbas.shef.ac.uk/resource/11/report_scores, which returns a 200 OK as normal...but the grades don't get to Blackboard.
We haven't updated our Numbas installation in a while, and the only thing I can think of that's changed is that our Blackboard system has been upgraded to 3900.21.0 recently. Does anyone know if there's any kind of issue with that release?
