php – Laravel 5：在扩展User的模型上查找函数

我正在使用Laravel 5并且有多个模型(患者,治疗师)从用户模型扩展.
我在DB中有一些虚拟数据(很少有治疗师,很少有患者).
当我想通过id检索治疗师时,我尝试通过Therapist :: find($id)这样做,但得到一个例外：

'IlluminateDatabaseQueryException' with message 'SQLSTATE[23000]: 
     Integrity constraint violation: 1062 Duplicate entry '' for key
    'users_email_unique' (SQL: insert into users`

几个问题：
1.为什么当我使用:: find函数时,它会尝试插入一个新用户？
2.如何在从User扩展的对象上使用:: find函数以获取每个模型的属性？

编辑

Ajax调用

/getTherapist

routes.php文件：

Route::get('/getTherapist','HomeController@getTherapist');

HomeController.php：

public function getTherapist()
{
    $user = Therapist::find(13);
    return $user->toArray();
}

完全例外：

> '' for key 'users_email_unique' (SQL: insert into `users`
