Symfony 4.3: FormType add extra "Entity" type

I want to create a form to register a new Number so i've created a NumberType(code below). But on the top of the form it adds a field as bellow :

<input type="text" id="number" name="number" required="required" class="form-control">

NumberType.php

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('created_by', EmailType::class, [
            'label' => 'Email *',
            'attr' => array(
                'placeholder' => '[email protected]',
            )
        ])
        ->add('title', TextType::class, [
            'label' => 'Titre *'
        ])
        ->add('value', TextType::class, [
            'label' => 'Valeur *'
        ])
        ->add('source', UrlType::class, [
            'label' => 'Source *'
        ])
        ->add('description', TextareaType::class, [
            'label' => 'Description',
            'required' => false,
            'attr' => array(
                'placeholder' => 'Description du chiffre proposé'                    
            )
        ])
        ->add('tags')
        ->add('recaptcha', EWZRecaptchaType::class)
        ->add('send', SubmitType::class, ['label' => 'Envoyer'])
    ;
}

AdminController.php

$number = new Number();
// Form creation
$form = $this->createForm(NumberType::class, $number);

When I call the url associated with my function in my controller I had an error which was saying

Can't convert Number to string

So I've added a __tostring() function but I don't understand why it needs it.

Thanks,

It looks like you use Symfony's NumberType instead your own.

Check the namespace at the top of AdminController file, which NumberType is being used.

If there's:

use Symfony\Component\Form\Extension\Core\Type\NumberType;

then it means you're using wrong class.

It should be something like:

use App\Some\Namespace\To\Your\NumberType;
