Denormalization_context groups doesnt work on Entity variables

API Platform version(s) affected: x.y.z

Description
My simple ApiResource entity denormalization group doesnt work

This is my entity

<?php

namespace App\Entity;

use ApiPlatform\Core\Annotation\ApiResource;
use App\Repository\UserRepository;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Serializer\Annotation\Groups;
use Symfony\Component\Serializer\Annotation\SerializedName;


  /**
   * @ApiResource(
   *     attributes={
   *     "normalization_context"={"groups"={"read"}},
   *     "denormalization_context"={"groups"={"write"}},
   * }
   * )
   * @ORM\Entity(repositoryClass=UserRepository::class)
   */

class User
  {
      /**
       * @ORM\Id
       * @ORM\GeneratedValue
       * @ORM\Column(type="integer")
       */
      private $id;
  
      /**
       * @ORM\Column(type="string", length=255)
       * @Groups("write")
       */
      private $first_name;
  
      /**
       * @Groups("write")
       * @ORM\Column(type="string", length=255, nullable=true)
       */
      private $last_name;
  
      /**
       * @ORM\Column(type="string", length=255)
       * @Groups("write")
       */
      private $api_key;
  
      /**
       * @Groups("read")
       * @ORM\Column(type="string", length=255, nullable=true)
       */
      private $full_name;
  
      public function getId(): ?int
      {
          return $this->id;
      }
  
      public function getFirstName(): ?string
      {
          return $this->first_name;
      }
  
      public function setFirstName(string $first_name): self
      {
          $this->first_name = $first_name;
  
          return $this;
      }
  
      public function getLastName(): ?string
      {
          return $this->last_name;
      }
  
      public function setLastName(?string $last_name): self
      {
          $this->last_name = $last_name;
  
          return $this;
      }
  
      public function getApiKey(): ?string
      {
          return $this->api_key;
      }
  
      public function setApiKey(string $api_key): self
      {
          $this->api_key = $api_key;
  
          return $this;
      }
  
      public function getFullName(): ?string
      {
          return $this->full_name;
      }
  
      public function setFullName(?string $full_name): self
      {
          $this->full_name = $full_name;
  
          return $this;
      }
  }

This is what I get

Possible Solution
There is a way to go around this issue just use denormalization groups on setter methods :

  /**
     * @param string $first_name
     * @Groups("write")
     * @return $this
     */
    public function setFirstName(string $first_name): self
    {
        $this->first_name = $first_name;

        return $this;
    }

   /**
     * @param string|null $last_name
     * @return $this
     * @Groups("write")
     */
    public function setLastName(?string $last_name): self
    {
        $this->last_name = $last_name;

        return $this;
    }

    /**
     * @param string $api_key
     * @return $this
     * @Groups("write")
     */
    public function setApiKey(string $api_key): self
    {
        $this->api_key = $api_key;

        return $this;
    }

Then it works just fine -

Also in this https://github.com/api-platform/api-platform/issues/1576 issue which is same problem but only with normalization_context not denormalization it suggest to clear cache with php bin/console cache:clear, i’ve tried it and it didn’t work.

looks like this was the correct answer:

Declare your properties with camel case instead of snake case. The serializer expects camelcase to match your properties with getters/setters.

@andrekutianski may you open a new issue with your case? Thanks.

~I believe that I resolve. In my case a moved the normalization_context to the operation:~

False-positive. Not worked at all.

#[ApiResource(
    mercure: true,
    normalizationContext: ['groups' => ['read']],
    collectionOperations: [
        'get',
        'post' => [
            'normalization_context' => ['groups' => ['write']],
        ],
    ],
)]

~Now the @context has the property and Hydra understudy which schema use.~
