I have a teacher who is trying to use the passback system to post grades to PowerSchool. However whenever she clicks the sync button she gets a Generic Error Code:  Assignment cannot be created for section with id=115793. There is no cross listings in the course, all grading categories have been imported from PowerSchool, and the teacher even has another similar course that will sync without issue (both classes have been setup the same way). Any ideas how to resolve this issue?
