How to include model in through query

[Алексей Данчин]

Hi! I have some relations for Lesson, User and Homework models:

Lesson.belongsToMany(User, { as: 'member', through: LessonMember });
User.belongsToMany(Lesson, { through: LessonMember });
LessonMember.belongsTo(Homework);

And I want to findAll Lesson, include members with together with their homework.

Lesson.findAll({
 include: [{
  model: User,
  as: 'member',
  through: {
   include: [{
    model: Homework
   }]
  }
 }]
})

But I real i get error: InternalServerError: Cannot read property 'indexOf' of undefined

How right? How get Lessons with members and homeworks?

For clarity: the code below works as expected.

Lesson.findAll({
 include: [{
  model: User,
   as: 'member',
   through: {
    attributes: ['homeworkId']
   }
 }]
})
