Error when running StringExtensionToConfigBuilderRector on simple configuration file

[reech-jeanphilippe]

PHP version: 8.3.9
Symfony version: 7.1
Rector version: 1.2.3

See demo here: https://getrector.com/demo/de776077-7f25-484f-bfea-1f5cf23a0443.

Applying the StringExtensionToConfigBuilderRector rule to this file:

<?php

declare(strict_types=1);

namespace Symfony\Component\DependencyInjection\Loader\Configurator;

use Http\Discovery\Psr17Factory;
use Psr\Http\Message\RequestFactoryInterface;
use Psr\Http\Message\ResponseFactoryInterface;
use Psr\Http\Message\ServerRequestFactoryInterface;
use Psr\Http\Message\StreamFactoryInterface;
use Psr\Http\Message\UploadedFileFactoryInterface;
use Psr\Http\Message\UriFactoryInterface;

return static function (ContainerConfigurator $containerConfigurator): void {
    $services = $containerConfigurator->services();

    $services->alias(RequestFactoryInterface::class, 'http_discovery.psr17_factory');

    $services->alias(ResponseFactoryInterface::class, 'http_discovery.psr17_factory');

    $services->alias(ServerRequestFactoryInterface::class, 'http_discovery.psr17_factory');

    $services->alias(StreamFactoryInterface::class, 'http_discovery.psr17_factory');

    $services->alias(UploadedFileFactoryInterface::class, 'http_discovery.psr17_factory');

    $services->alias(UriFactoryInterface::class, 'http_discovery.psr17_factory');

    $services->set('http_discovery.psr17_factory', Psr17Factory::class);
};

results in this error:

Thanks.

Thank you for your report and demo link!

We'll need a failing test case in a pull-request, so we have it covered in Rector.
You can click "Create a Test" button at demo page.

[reech-jeanphilippe]

Wow, you're fast !

I don't see this button on the demo page.

[samsonasik]

The button not shown due to crash, so rule list not shown as well, you can add fixture to https://github.com/rectorphp/rector-symfony/tree/main/rules-tests/CodeQuality/Rector/Closure/StringExtensionToConfigBuilderRector/Fixture , I think this should be skipped for no extension definition.

[reech-jeanphilippe]

OK, I'll do that tomorrow.

Thanks again.
