What are you doing?

If I set rejectOnEmpty to true during initialization I cannot override it in a query anymore. I would guess the error is https://github.com/sequelize/sequelize/blob/master/lib/model.js#L1681

const sequelize = new Sequelize({
  define: {
    rejectOnEmpty: true
  }
});

model.findAll({
  rejectOnEmpty: false
});

What do you expect to happen?

findAll resolves with []

What is actually happening?

findAll rejects with SequelizeEmptyResultError
