match 聚合查询，我想过滤数组，nin和in为什么不生效？ 关联查询后如何过滤数组？

 const users = await userDb.where({
            openId: OPENID,
        }).get();
        const currentUser = users.data[0] || {}
        const where = {
            active: true,
            openId: $.neq(OPENID), // 不能看到自己的小程序
        }
        if (taskType === 'taskRecord') {
            if (users.data && users.data.length) { // 只看自己点过的小程序
                where.accessApp = _.in(currentUser.accessApp)
                console.log('查询点过的', currentUser)
            }
        } else {
            // 查看最新笔记
            where.flowers = $.gt(0);  // 小红花必须大于0
            if (users.data && users.data.length) { // 过滤已看过的小程序
                where.accessApp = _.nin(currentUser.accessApp)
                console.log('查询最新笔记', currentUser)
            }
        }
        const lookup = {
            from: 'user',
            localField: 'openId',
            foreignField: 'openId',
            as: 'userInfo',
        }
        const addFields = {
            flowers: '$userInfo.flowers',
            accessApp: "$userInfo.accessApp"
        }
        const countAggregateInstance = task.aggregate().lookup(lookup);
        // 统计数量
        const totalCount = await countAggregateInstance.addFields(addFields).match(where).count('totalCount').end();
        // 分页查询
        const data = await task
            .aggregate()
            .lookup(lookup)
            .addFields(addFields)
            .match(where)
            .skip((pageIndex - 1) * pageSize)
            .limit(pageSize)
            .end()
