I try to remove as much code as possible from my command, to reproduce the problem. I can reproduce it with this sample code:

<?php

namespace App\Command\Alarms;

use Symfony\Component\Console\Attribute\AsCommand;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Output\OutputInterface;

#[AsCommand(
    name: 'ack:alarm',
    description: '',
)]
class AckAlarmCommand extends Command
{
    #[\Override]
    protected function configure(): void
    {
        $this
            ->addOption(
                name: 'startDate',
                mode: InputOption::VALUE_REQUIRED,
                description: 'non empty description needed to reproduce the bug',
            );
    }

    #[\Override]
    protected function execute(InputInterface $input, OutputInterface $output): int
    {
        return Command::SUCCESS;
    }
}

Surprisingly, a non empty description for the startDate option is needed to reproduce the bug !

I hope it helps (I just followed rector instructions when there is a crash)

Thanks!
Fred

Thank you for your report!

We'll need an isolated failing demo link from: http://getrector.com/demo,
that way we can reproduce the bug.

[fcharrier]

I can reproduce the bug on my local environment with this config: https://getrector.com/demo/0bdcc43b-0634-4e5d-a99d-3cc5f4113f65

Hope it helps

[TomasVotruba]

Thanks for the link. It should be able to crash on demo as well, or we're unable to fix the bug.

What is the PHP and Symfony version you're using? Does it happen on differnt PHP/Symfony versions as well?

[fcharrier]

I understand, I don't know why it crashes on my computer, but not in this demo environment

I use PHP 8.4.15, and Symfony 7.3.8

[fcharrier]

I see the rector version used by your link is "Rector version: 2e1e9c - released at 2025-12-14 18:50"

Is there any chance "my" bug has been solved in a recent version?
I'm using 2.2.14 locally
I checked, it's the last available version, tagged a week ago (dec 9). But "2e1e9c" is latest...

InvokableCommandInputAttributeRector is removed from symfony 7.3 set at PR:

• Remove InvokableCommandInputAttributeRector from set rector-symfony#901

[samsonasik]

Ok, reproduced with register it InvokableCommandInputAttributeRector via withRules()

https://getrector.com/demo/d19268e2-5a54-45d0-b856-abfb66a121f1

since InvokableCommandInputAttributeRector removed from sets on latest dev-main

[fcharrier]

Well done @samsonasik! It explains why I can't reproduce the bug initialy with getrector.com!

Thank you so much for your help :)
