EntityType - Can not use query_builder - symfony

Question

I have a problem with my FormType in Symfony. I have a field that allows me to check one or more checkboxs whose values represent objects from another entity. (In this case, types of holidays).
Except that I do not want to display them all, so I use a query_builder as such:
->add('typesConges', EntityType::class, [
'class' => TypeConge::class,
'choice_label' => 'nom',
'expanded' => true,
'multiple' => true,
'query_builder' => function (TypeCongeRepository $repoTypes) {
return $repoTypes->getTypesNotNull();
}
])
But it raised this error :
The name "Heures supp" contains illegal characters. Names should start
with a letter, digit or underscore and only contain letters, digits,
numbers, underscores ("_"), hyphens ("-") and colons (":").
However, if I remove the query_builder, I have all my TypeConge ( the "Heures supp" aswell).
GestionSoldes.php
<?php
namespace App\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
class GestionSoldes
{
/**
* Types de congés
*
* #var Collection|TypeConge[]
*/
private $typesConges;
/**
* All types
*
* #var boolean
*/
private $allTypes;
public function __construct()
{
$this->typesConges = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
/**
* #return Collection|TypeConge[]
*/
public function getTypesConges(): Collection
{
return $this->typesConges;
}
public function addTypesConge(TypeConge $typesConge): self
{
if (!$this->typesConges->contains($typesConge)) {
$this->typesConges[] = $typesConge;
}
return $this;
}
public function removeTypesConge(TypeConge $typesConge): self
{
if ($this->typesConges->contains($typesConge)) {
$this->typesConges->removeElement($typesConge);
}
return $this;
}
public function getAllTypes(): ?bool
{
return $this->allTypes;
}
public function setAllTypes(bool $allTypes): self
{
$this->allTypes = $allTypes;
return $this;
}
}
Form:
<?php
namespace App\Form;
use App\Entity\TypeConge;
use App\Entity\GestionSoldes;
use App\Repository\TypeCongeRepository;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\CheckboxType;
class GestionSoldesType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('typesConges', EntityType::class, [
'class' => TypeConge::class,
'choice_label' => 'nom',
'expanded' => true,
'multiple' => true,
'query_builder' => function (TypeCongeRepository $repoTypes) {
return $repoTypes->getTypesNotNull();
}
])
->add('allTypes', CheckboxType::class, [
'required' => false,
'label' => 'Tous les types de congés',
'label_attr' => [
'class' => 'custom-control-label',
'for' => 'allTypes'
],
'attr' => [
'class' => 'custom-control-input',
'id' => 'allTypes'
]
])
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => GestionSoldes::class,
]);
}
}
My repo function:
/**
* Retourne les types de congés qui ont un solde initial différent de null ( pour form EntityType )
*
* #return void
*/
public function getTypesNotNull()
{
return $this->createQueryBuilder('t')
->where('t.soldeInitial is not null')
->orderBy('t.nom', 'ASC');
}

As it shows no errors when you remove te query-builer, The problem must come from the query-builder.
As the only moment you use the property nom in the query-builder is in
->orderBy('t.nom', 'ASC');
The problem is here.
Make sure that your ORM (doctrine or else) is ok with string containing spaces.
to verify my point try to remove the orderBy from your query
