Sequelize.js Sequelize-聚合函数多对多

我与我的

用户

和

组织

表之间的连接

组织成员

存在多对多关系。我正在尝试创建一个查询，该查询统计

组织\u id

与特定整数匹配的用户id的数量。我这边的预期结果是一行，其中用户Id的总数作为一列，组织Id作为第二列。我以为我可以通过以下查询实现这一点，但我收到一个错误，

未处理的拒绝SequelizeDatabaseError:列“user.user\u id”必须出现在GROUP BY子句中或用于聚合函数

。为什么要这样做？很抱歉，缺乏使用SQL的经验，包括聚合和多对多

查询：

models.User.findAll({
        attributes: [[sequelize.fn('COUNT', sequelize.col('user.user_id')), 'user_count']],
        include: [{
            model: models.Organization,
            where: {
                organizationId: req.session.organizationId
            },
            attributes: ['organization_id'],
            group: ['organiztion.organization_id']
