I have created this model transformer:

<?php

namespace App\AutoMapper;

use App\ApiResource\JobApi;
use App\Entity\Job;
use AutoMapper\Transformer\CustomTransformer\CustomModelTransformerInterface;
use Symfony\Component\PropertyInfo\Type;

final readonly class JobToJobApiCustomTransformer implements CustomModelTransformerInterface
{
    public function supports(array $sourceTypes, array $targetTypes): bool
    {
        return $this->hasType($sourceTypes, Job::class) && $this->hasType($targetTypes, JobApi::class);
    }

    /**
     * @param object|array<int, mixed> $source
     * @return JobApi
     * @throws \Exception
     */
    public function transform(object|array $source): JobApi
    {
        if (!($source instanceof Job)) {
            throw new \Exception(sprintf('Expected instance of %s, %s given', Job::class, gettype($source)));
        }

        $target = new JobApi();

        $target->setId($source->getId());
        $target->setUser($source->getUser());
       
        // more...

        return $target;
    }

    /**
     * @param Type[] $types
     * @param class-string $class
     */
    private function hasType(array $types, string $class): bool
    {
        foreach ($types as $type) {
            if ($type->getClassName() === $class) {
                return true;
            }
        }

        return false;
    }
}

And using it as:

/** @var ArrayCollection<int, JobApi> $jobs */
$jobs = new ArrayCollection();

/** @var Job $item */
foreach ($pagination->getItems() as $item) {
    /** @var JobApi $job */
    $job = $this->autoMapper->map($item, JobApi::class);
    $jobs->add($job);
}

it just doesn't find the custom transformer at all. It does find custom property transformers as I use them but this custom model transformer is nowhere to be applied...

I tested this for a few hours, no matter how I put it, I can't trigger the custom transformer at all.

@Korbeil - can you please check this?

On a new Symfony 7 project, composer require works until we reach "Executing script cache:clear" and then fails with:

In CheckExceptionOnInvalidReferenceBehaviorPass.php line 85:
The service "automapper.property_info.cache.inner" has a dependency on a non-existent service "property_info.phpstan_extractor". Did you mean one of these: "property_info.serializer_extractor", "property_info.reflection_extractor"?

This turns out to be an error Google knows nothing about :)

Tested with bundle versions v8.0.2 and dev-main 9c51bde

Description:
Here is the error that I'm encountering while trying to install the automapper-bundle in Symfony:
PHP Fatal error: Class AutoMapper\Extractor\MapToContextPropertyInfoExtractorDecorator contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Symfony\Component\PropertyInfo\Extractor\ConstructorArgumentTypeExtractorInterface::getTypeFromConstructor) in /Users/mouradchab/Sites/sf71-serializer-turbo-2/vendor/jolicode/automapper/src/Extractor/MapToContextPropertyInfoExtractorDecorator.php on line 22

Steps to reproduce:
Create a new Symfony project using version 7.1.x-dev
Install the automapper-bundle with composer

See error

My environment details:
Operating System: macOS Sonoma
PHP version: 8.2

I am very new to using this bundle, so I might be wrong, but after working with it for a day, it seems that in dev mode, if the mapped class files have been generated, they're there to stay, you need to clear the app cache in order to have changes reflected. This isn't really a good DX on dev, they should be generated only if the sources/targets/transformers have changed.
