System error: "Return value of RectorPrefix202305\Nette\Utils\Reflection::getUseStatements() must be of the type array, null returned"

Got this error by running rector with --debug on an Entity class using ApiPlatform resource class

<?php

declare(strict_types=1);

use Rector\Config\RectorConfig;
use Rector\Set\ValueObject\LevelSetList;
use Rector\Set\ValueObject\SetList;
use Rector\Symfony\Set\SymfonySetList;
use Rector\Doctrine\Set\DoctrineSetList;
use Rector\Core\ValueObject\PhpVersion;

return static function (RectorConfig $rectorConfig): void {
    // define sets of rules
    $rectorConfig->sets([
        LevelSetList::UP_TO_PHP_82,
    ]);

    $rectorConfig->importNames();
    $rectorConfig->importShortClasses(false);
    $rectorConfig->phpVersion(PhpVersion::PHP_82);

    $rectorConfig->paths([
        __DIR__ . '/src',
    ]);

};

Could you provide reproducible test on https://getrector.com/demo/ , or we need simple reproducible code for that that show error, with only 1 or 2 rules, you can provide reproducible github repo, better with github action running

@samsonasik unfortunately, I am not sure I can, simply because I don't actually understand the error. I just followed the instructions on the error message and filed this bug report.
What I can add is that I tried to run this rector script settings using smaller sets of directories from same project and got less errors like this, ie, it seems that some conflicts come from changes done by rector itself on other classes that might be dependencies of further along (in the tree) classes.
I understand it's difficult to check these issues with no more data, and I would totally understand there's nothing you can do to help.

Ok, I am closing as not reproducible. You can come back with reproducible repo, better with github action running when you have a chance.

Thank you.
