Hey,

wenn ich auf “Zur Kasse” klicke erhalte ich folgende Symfony Exception ([TypeError)](https://sunshine-germany.de/checkout/register#trace-box-1).

“Return value of Shopware\Storefront\Page\MetaInformation::getMetaTitle() must be of the type string, null returned”

```

Um den Fehler zu beheben muss eine Typkonvertierung durchgeführt werden.

```
In vendor/shopware/storefront/Page/MetaInformation.php Zeile 51

```

return (string)$this-\>metaTitle;
