Hallo,

nach dem Update auf 6.4.0 habe ich auf der Storefront folgenden Fehler:

# Attempted to load class „ReadProtected“ from namespace „Shopware\Core\Framework\DataAbstractionLayer\Field\Flag“.

Did you forget a „use“ statement for another namespace?

Ins Backend kann ich mich zwar einloggen, werde aber auf eine leere Seite redirected.

Hat das Problem schon jemand???

Lg

ich hab das selbe problem seit kurzem mit 6.3.5.4.

mein workaround ist statt der domain die server IP zu nutzen, dann gehts.

Also ich hatte das problem auch und habe festegestellt, dass eine Datei fehlte und zwar die /vendor/shopware/core/Framework/DataAbstractionLayer/Field/Flag/ReadProtected.php mit enstprechendem Inhalt.

```auto
<?php declare(strict_types=1);

namespace Shopware\Core\Framework\DataAbstractionLayer\Field\Flag;

use Shopware\Core\Framework\Api\Context\AdminApiSource;
use Shopware\Core\Framework\Api\Context\SalesChannelApiSource;

class ReadProtected extends Flag
{
    private const BASE_URLS = [
        AdminApiSource::class => '/api/v',
        SalesChannelApiSource::class => '/sales-channel-api/v',
    ];

    /**
     * @var array[string]string
     */
    private $protectedSources = [];

    public function __construct(string ...$protectedSources)
    {
        foreach ($protectedSources as $source) {
            $this->protectedSources[$source] = self::BASE_URLS[$source];
        }
    }

    public function getProtectedSources(): array
    {
        return array_keys($this->protectedSources);
    }

    public function isBaseUrlAllowed(string $baseUrl): bool
    {
        foreach ($this->protectedSources as $url) {
            if (mb_strpos($baseUrl, $url) !== false) {
                return false;
            }
        }

        return true;
    }

    public function isSourceAllowed(string $source): bool
    {
        return !isset($this->protectedSources[$source]);
    }

    public function parse(): \Generator
    {
        yield 'read_protected' => [
            array_keys($this->protectedSources),
        ];
    }
}

Hi, Have anybody got the solution for this, I am also getting this error after shopware 6.4.1 update.

{„errors“:[{„code“:„0“,„status“:„500“,„title“:„Internal Server Error“,„detail“:„Attempted to load class \u0022Instagram\u0022 from namespace \u0022Vinkla\Instagram\u0022.\nDid you forget a \u0022use\u0022 statement for another namespace?“}]}

Any Idea or Solution?
