make:serializer:normalizer Passing null to parameter #2 ($replace) of type array|string is deprecated

[bechir]

when I make FooNormalizer with make:serializer:normalizer, I got this output:

<?php

namespace App\Serializer\Normalizer;

use Symfony\Component\Serializer\Normalizer\CacheableSupportsMethodInterface;
use Symfony\Component\Serializer\Normalizer\NormalizerInterface;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;

class FooNormalizer implements NormalizerInterface, CacheableSupportsMethodInterface
{
    // ...
    public function supportsNormalization($data, string $format = null, array $context = []): bool
    {
        return $data instanceof \App\Entity\
Deprecated: str_replace(): Passing null to parameter #2 ($replace) of type array|string is deprecated in vendor/symfony/maker-bundle/src/Resources/skeleton/serializer/Normalizer.tpl.php on line 24
Foo;
    }
}

PHP version: 8.1
Maker v1.45.0

Solution

Replace null with '' ?

return $data instanceof \App\Entity\<?= str_replace('Normalizer', '', $class_name) ?>;
