Symfony version(s) affected: 3.4.23

Description

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('arr', 'Symfony\Component\Form\Extension\Core\Type\CollectionType', [
            'entry_type' => TextType::class,
            'allow_add' => true
        ])
       ;

    $builder->get('arr')
        ->addModelTransformer(new CallbackTransformer(
            function ($value) {
                return json_decode($value, true);
            },
            function ($value) {
                return json_encode($value);
            }
        ));
}

Expected argument of type "array or (\Traversable and \ArrayAccess)", "string" given

Why didn't convert the string to an array?

Hello,
I guess this is a bug on the 3.4 version.
I have the same error when i upgraded to 3.4.
Expected argument of type "array or (\Traversable and \ArrayAccess)", "string" given, I use a ModelTransformer to convert an array to a string, with a collectionType. The same code works with the 3.3 version.
Thank you

@mayro Please open a new issue if you think that you found a bug with some instructions on how we can reproduce the issue (best would be a small example application).
