In my course, there is one sub-section that is hidden from the learner and the due date is passed. Now when I am generating the grade report I am getting the KeyError of
KeyError: BlockUsageLocator(CourseLocator(u'test', u'test', u'2019', None, None), u'sequential', u'4b1e0e0818dc4ed09a27eb7374409999')
If I unhide this subsection then I can able to download the report.
Is there any other way to generate a report?
is this default behavior of Open edX?
