As the documentation suggests I wrote this service to add the uuid to the normalized object:

<?php
namespace App\Serializer;

use InvalidArgumentException;
use Symfony\Component\Serializer\Normalizer\DenormalizerInterface;
use Symfony\Component\Serializer\Normalizer\NormalizerInterface;
use Symfony\Component\Serializer\SerializerAwareInterface;
use Symfony\Component\Serializer\SerializerInterface;

final class ApiNormalizer implements NormalizerInterface, DenormalizerInterface, SerializerAwareInterface
{
    private DenormalizerInterface|NormalizerInterface $decorated;

    public function __construct(NormalizerInterface $decorated)
    {
        if (!$decorated instanceof DenormalizerInterface) {
            throw new InvalidArgumentException(sprintf('The decorated normalizer must implement the %s.', DenormalizerInterface::class));
        }

        $this->decorated = $decorated;
    }

    public function supportsNormalization($data, $format = null)
    {
        return $this->decorated->supportsNormalization($data, $format);
    }

    public function normalize($object, $format = null, array $context = [])
    {
        $data = $this->decorated->normalize($object, $format, $context);
        if(method_exists($object, 'getUuid') && is_array($data)){
            $data['uuid'] = $object->getUuid();
        }
        return $data;
    }

    /**
     * @param mixed $data
     * @param string $type
     * @param null $format
     *
     * @return bool
     */
    public function supportsDenormalization($data, $type, $format = null)
    {
        return $this->decorated->supportsDenormalization($data, $type, $format);
    }

    public function denormalize($data, $type, $format = null, array $context = [])
    {
        return $this->decorated->denormalize($data, $type, $format, $context);
    }

    public function setSerializer(SerializerInterface $serializer)
    {
        if($this->decorated instanceof SerializerAwareInterface) {
            $this->decorated->setSerializer($serializer);
        }
    }
}

And services.yaml

App\Serializer\ApiNormalizer:
    # By default .inner is passed as argument
    decorates: 'api_platform.jsonld.normalizer.item'

But suddenly (until yesterday everything was fine) it starts to give me this error when I run composer or cache clear
