CakePHP3：SELECT列表不在belongsToMany关联中的GROUP BY中

Question

我已经遇到过这样的问题但我不明白在这种情况下如何定义group()：

我有以下表格：

Articles {
    'id',
    'name',
}

Categories {
    'id',
    'name'
}

ArticlesCategories {
    'article_id',
    'category_id'
}

查询是：

$seconds = $this->Categories->find()
->contain([
    'Articles' => function ($q) {
        return $q->distinct(['Articles.id']);
    }
])
->where([
    'Categories.name IN' => $themeNames,
->all();

错误是：

Exception: SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #3 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'base.ArticlesCategories.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by in [/var/www/mySite/vendor/cakephp/cakephp/src/Database/Statement/MysqlStatement.php, line 36]

因为问题似乎来自联接表，我不知道如何编写group()子句。
