Mask that identifies which fields on the course work material to update. This field is required to do an update. The update fails if invalid fields are specified. If a field supports empty values, it can be cleared by specifying it in the update mask and not in the course work material object. If a field that does not support empty values is included in the update mask and not set in the course work material object, an INVALID_ARGUMENT error is returned.
The following fields may be specified by teachers:
title
description
state
scheduledTime
topicId
This is a comma-separated list of fully qualified names of fields. Example: "user.displayName,photo".
