Expected argument of type "string", MyEntity given

I faced a problem when created a dropdown (category, subcategory) instead of input text fields in FormBuilderInterface When I change it back to text input all working good.

Here is my code for FormType

namespace Expatservice\ManagerBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\Extension\Core\Type\FileType;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Doctrine\ORM\EntityRepository;

class ServiceType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('title')
            ->add('category', EntityType::class, array(
                'class' => 'ExpatserviceCategoryBundle:Category',
                'query_builder' => function (EntityRepository $er) {
                    return $er->createQueryBuilder('c')
                    ->where('c.parent = 0')
                    ->orderBy('c.title', 'ASC');
                },
                'choice_value' => 'title',
                'choice_label' => 'title'
            ))
            ->add('subcategory', EntityType::class, array(
                'class' => 'ExpatserviceCategoryBundle:Category',
                'query_builder' => function (EntityRepository $er) {
                    return $er->createQueryBuilder('c')
                    ->where('c.parent = 2')
                    ->orderBy('c.title', 'ASC');
                },
                'choice_value' => 'title',
                'choice_label' => 'title'
            ))
            ->add('description')
            ->add('image', FileType::class, array('data_class' => null, 'required'=>false));
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaultOptions(array('data_class' => 'Expatservice\ManagerBundle\Entity\Service'));
    }

    public function getName()
    {
        return 'expantservice_managerbundle_service';
    }
}

I understand the problem, but can't figure out how to fix it and don't found nothing in internet.

I should use __toString() magic function to get right data type when handle my form submitting.

To be sure that we'll get string, Entity part should look like this:

/**
 * Get title
 *
 * @return string
 */
public function getTitle()
{
    return $this->title;
}

public function __toString() {
    return $this->title;
}
