patch(courseId, itemId, attachmentId, body=None, postId=None, updateMask=None, x__xgafv=None)
Updates an add-on attachment. Requires the add-on to have been the original creator of the attachment. This method returns the following error codes: * `PERMISSION_DENIED` for access errors. * `INVALID_ARGUMENT` if the request is malformed. * `NOT_FOUND` if one of the identified resources does not exist.

Args:

  postId: string, Required. Identifier of the post under which the attachment is attached.
  updateMask: string, Required. Mask that identifies which fields on the attachment to 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 `AddOnAttachment` object. If a field that does not support empty values is included in the update mask and not set in the `AddOnAttachment` object, an `INVALID_ARGUMENT` error is returned. The following fields may be specified by teachers: * `title` * `teacher_view_uri` * `student_view_uri` * `student_work_review_uri` * `due_date` * `due_time` * `max_points`
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format
