Как ссылаться на столбец родительской модели из включения в Sequelize?

Проблема

Всем привет. Я новичок в Sequelize и получаю несколько строк из InterestModel, используя массив идентификаторов интересов - не все интересы совпадают с categoryId. Для каждого интереса я пытаюсь включить MediaModel строк, которые не разделяют categoryId с возвращаемым процентом.

Как мне сослаться на свойство categoryId объекта родительский запрос InterestModel из include?

Я попытался использовать решения из этого сообщения SO , но я продолжаю получать некоторые варианты ошибки Unknown column 'interest.categoryId' in 'where clause'.

Запрос

Вот запрос с различными попытками, которые я пробовал. 

const interestIds: [ 2, 4, 6, ...];

const query = {
  where: { id: interestIds },
  attributes: [ 'id', 'userId', 'categoryId' ], // <-- this is categoryId
  include: [
    {
      model: UserModel,
      as: 'user',
      attributes: [
        'id',
        'avatarType',
        'avatarUrls',
        'firstName',
        'bio',
      ],
      include: [
        {
          model: InterestModel,
          as: 'interests',
          attributes: [ 'categoryId' ],
        },
        {
          model: MediaModel,
          // Attempts:
          // where: database.literal('media.categoryId != interest.categoryId'), // ?
          // where: { categoryId: { [Op.not]: { [Op.col]: 'InterestModel.categoryId' } },
          // where: { categoryId: { [Op.not]: { [Op.col]: 'Interest.categoryId' } },
          // where: { categoryId: { [Op.not]: { [Op.col]: 'interest.categoryId' } },
          // where: { categoryId: { [Op.not]: { [Op.col]: '`interest`.`categoryId`' } },
          attributes: [ 'userId', 'urls' ],
          order: database.literal('rand()'),
          limit: 6,
        },
      ],
    },
  ],
};

return InterestModel.findAll(query).then(interests => { ...etc });

Ведение журнала

И вот соответствующий вывод журнала из Sequelize:
