demo with old config build

[staabm]

I tried running the online demo with

<?php

final class HelloWorld
{
    private readonly DateTime $now;

    public function __construct(
        ?DateTime $now = null 
    ) {
        $this->now = $now ?? new DateTime();
    }
}

and config

<?php

use Rector\Config\RectorConfig;
use Rector\TypeDeclaration\Rector\Property\TypedPropertyFromAssignsRector;

return static function (RectorConfig $rectorConfig): void {
    $rectorConfig->sets([
        \Rector\Set\ValueObject\SetList::TYPE_DECLARATION,
    ]);
}

and when submitting the form I only get a http 500 error page?
I would expect a more helpful error message.

does the old config style no longer work on the demo?

ahh I just realized that I have a linting error in my config. it is missing a ; at the end.

sounds like something the demo could provide a more helpful error message :-)
