The method createRequest() does not exist on GuzzleHttp\Client. Did you maybe mean request()?

            $response = $this->packResponse($guzzleResponse);

$guzzleResponse is of type object<Psr\Http\Message\ResponseInterface>, but the function expects a null|object<GuzzleHttp\Message\ResponseInterface>.

It seems like $exception->getResponse() targeting GuzzleHttp\Exception\RequestException::getResponse() can also be of type object<Psr\Http\Message\ResponseInterface>; however, Commercetools\Core\Client\Adapter\Guzzle5Adapter::packResponse() does only seem to accept null|object<GuzzleHttp\Message\ResponseInterface>, maybe add an additional type check?
