我是Laravel Eloquent ORM使用PgSql，当我使用with()方法是返回错误。
SQLSTATE [42883]：未定义函数：7错误：操作员不存在：uuid = integer行1：
Laravel版本10.7.1 Php版本8.1.17
下面是表的结构，由于某种原因，我改变了表名。

parents
--------
id (uuid)
name (string)
user_id (uuid)
description (text)

details
---------
id (uuid)
parent_id (uuid)
title (stirng)
description (tinytext)

下面是来自控制器的代码

/**
     * Display the specified resource.
     */
    public function show(string $id)
    {
        $this->authorize('viewParent', \App\Models\Parent::class);

        $model = \App\Models\Parent::with(['user', 'parentChilds'])->findOrFail($id);

        return view("$this->view.show", [
            'model' => $model,
            'title' => "$this->title",
            'route' => $this->route,
        ]);
    }

但是当我使用$modelParent->parentChilds()->createMany([...data])方法时，它没有返回任何错误。
