Hello to everybody,
we got some problem with the Shopware [AppTemplate] ([GitHub - shopware/AppTemplate](https://github.com/shopware/AppTemplate)) and the Shopware 6 Test-Instance (The instance to test bevor you give an App to the Review).
When trying to authenticate with the Shopware 6 app test environment to send a request to the Shopware instance, the core code of the AppTemplate throws an exception. This is thrown by a 302 Http status code:
```auto

The calling code:
```auto
static function getCurrencies(ShopClient $client)
{
$currencyResponse = $client->sendRequest(new Request(
'POST',
'api/search/currency',
body: json_encode([])
));
return json_decode($currencyResponse->getBody()->getContents(), true);
}
```
