did you add the same normalization group to every property in your entity?

I tested in both cases and it doesn't work, with all property in the same group and with 2 propertie in the group and here is only one group in this entity.

from the little you provided, the route seems to be returning the expected result. Can you post the entire entity here? I think you are messing up somewhere with the denormalization groups.

I do not have denormalization groups just a normalization, it is not necessary to create a group. my code worked on symfony 5.0 and 4.4

well, if you don't want to post your entity, I don't know how to help. I'm running 5.1 and I have no issues. Do you have custom normalizers defined?

`<?php

namespace App\Entity;

use ApiPlatform\Core\Annotation\ApiResource;
use App\Repository\QuestionRepository;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Serializer\Annotation\Groups;

/**

• @ApiResource(normalizationContext={"groups"={"read:quest"}}, collectionOperations={"get"}, itemOperations={"get"})

• @Orm\Entity(repositoryClass="App\Repository\QuestionRepository")
  /
  class Question
  {
  /*

  • @Orm\Id()
  • @Orm\GeneratedValue()
  • @Orm\Column(type="integer")
  • @groups({"read:quest"})
    */
    private $id;

  /**

  • @Orm\Column(type="string", length=255)
  • @groups({"read:quest"})
    */
    private $libelle;

  /**

  • @Orm\OneToMany(targetEntity=Reponse::class, mappedBy="idQuestion", orphanRemoval=true)
  • @groups({"read:quest"})
    */
    private $reponses;

  public function __construct()
  {
  $this->reponses = new ArrayCollection();
  }

  public function getId(): ?int
  {
  return $this->id;
  }

  public function getLibelle(): ?string
  {
  return $this->libelle;
  }

  public function setLibelle(string $libelle): self
  {
  $this->libelle = $libelle;

   return $this;
  

  }

  /**

  • @return Collection|Reponse[]
    */
    public function getReponses(): Collection
    {
    return $this->reponses;
    }

  public function addReponse(Reponse $reponse): self
  {
  if (!$this->reponses->contains($reponse)) {
  $this->reponses[] = $reponse;
  $reponse->setIdQuestion($this);
  }

   return $this;
  

  }

  public function removeReponse(Reponse $reponse): self
  {
  if ($this->reponses->contains($reponse)) {
  $this->reponses->removeElement($reponse);
  // set the owning side to null (unless already changed)
  if ($reponse->getIdQuestion() === $this) {
  $reponse->setIdQuestion(null);
  }
  }

   return $this;
  

  }
  }

this is my entity i don't have custom normalizer

did you find a solution ?

not really, I downgraded symfony to 5.0 and it works, I haven't tried again since

Try to run ./bin/console cache:clear

there is no cache that does not fix the bug

for me ./bin/console cache:clear solved the issue
symfony :5.1

after trying it works! thanks for the help !

Worked also for me !!
Is there a way to disable this cache in dev environment ?
Thanks

@dParadiz clearing the cache solved my problem after 3 hours of wondering why a simple get was not returning the entity data!

Same problem but with post operation, cache clearing does not fix it...

Bus somewhy if I add write group to setter method it magically works...

    /**
     * The description of the cheese as raw text.
     * @Groups({"write"})
     */
    public function setFirstName(string $first_name): self
    {
        $this->first_name = $first_name;

        return $this;
    }

did you add the same normalization group to every property in your entity?

In my own case, I did, out of 5, only two appeared in the api documentation.
