مطلوب. قناع يحدِّد الحقول التي يجب تعديلها في المرفق يتعذّر إجراء التعديل في حال تحديد حقول غير صالحة. إذا كان الحقل يتيح القيم الفارغة، يمكن محو محتواه من خلال تحديده في قناع التعديل وليس في عنصر AddOnAttachment. إذا تم تضمين حقل لا يقبل القيم الفارغة في قناع التعديل ولم يتم ضبطه في عنصر AddOnAttachment، يتم عرض خطأ INVALID_ARGUMENT.
يمكن للمعلّمين تحديد الحقول التالية:
title
teacherViewUri
studentViewUri
studentWorkReviewUri
dueDate
dueTime
maxPoints
هذه قائمة مفصولة بفواصل تتضمّن أسماء حقول مؤهَّلة بالكامل. مثال: "user.displayName,photo"
