Laravel Попытка получить свойство не-объекта Error

Question

У меня есть две таблицы выглядит следующим образом

empPf

id 
emp_id 
emp_name 
uan 
kyc 

empyc

id 
emp_id 
doc_type 
doc_number 

Теперь у меня есть две модели

empPf

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 

class empPf extends Model 
{ 
    protected $table = 'empPf'; 
    protected $primaryKey = 'emp_id'; 

    public function kyc(){ 

      return $this->hasMany('App\empKyc','emp_id'); 

     } 
} 

empKyc

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 

class empKyc extends Model 
{ 
    protected $table = 'empKyc'; 
    //protected $primaryKey = 'emp_id'; 

    public function pf(){ 

      return $this->belongsTo('App\empPf','emp_id'); 

     } 
} 

Я пытаюсь сделать следующий код в мой контроллер

public function getPf(){ 
     Session::put('activemenu', 'emp_ss'); 

     $pfs = empPf::with(array('kyc'))->get(); 

     foreach ($pfs as $value) { 
       dd($value->kyc[0]->emp_id); 
     } 

    } 

Я получаю ошибку

Trying to get property of non-object

Любая помощь будет оценена

Вы должны проверить, если ваш Пл модель имеет любую связанную ЗСК первый:

foreach ($pfs as $value) { 
    if ($value->kyc->count()) { 
     dd($value->kyc[0]->emp_id); 
    } 
}
