Error Typed property Foo::$bar must not be accessed before initialization

Question

I am using php8.2 in a Symfony 6.4 app. I have a DTO, which is defined as follows:

final class Store
{
    public function __construct(
        public readonly string $storeNumber,
        public readonly bool $central,
        public readonly string $name,
        public readonly ?string $city = null,
        public readonly ?string $zip = null,
        public readonly ?string $street = null,
        public readonly ?bool $published = null,
    ) {
    }
}

The only time the constructor is called is in a method, where I match a stdClass object to this class:

class StoreHelper
{
    public static function mapFromFetchedData(stdClass $store): Store
    {
        $city = ($store->address && $store->address->city) ? $store->address->city : null;
        $zipCode = ($store->address && $store->address->zipCode) ? $store->address->zipCode : null;
        $street = ($store->address && $store->address->street) ? $store->address->street : null;
        $published = ($store->published) ?: null;

        return new Store(
            storeNumber: $store->number,
            central: $store->central,
            name: $store->name,
            city: $city,
            zip: $zipCode,
            street: $street,
            published: $published,
        );
    }
}

Locally this runs fine (nice!), but on the production server I get this error and I have no clue why and what I can do against it:

 Error thrown while running command "'app:personal-sub'". Message: "Typed property App\Store\Store::$published must not be accessed before initialization"

This happens when I run a command on the console, which at some point calls this class.

Originally I had not set the null default values, so I tried that and it made no difference at all. As I understand it setting all properties in the constructor should avoid this problem even if the value is only null, when it is set.

How can I avoid this error?
