Behat functional test stop Symfony HttpKernal redirects - rest

Question

I'm using Behat to test a REST API my team has developed. When a particular resource is created the API returns a 201 and a Location header in the response.
The API was developed using using Symfony5 and it's using the Symfony HttpKernel as the client:
$kernel->handle($request);
I would like to assert through my behat test that it returns a 201 and the headers contains the Location. However the client is automatically following the Location header and as such I can't verify that.
Is there a way to turn off following redirects using the existing kernel component? I've not been able to find a way to do this.

You can create your own context and check the Response
<?php declare(strict_types=1);
namespace App\Tests\Features\Context;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpKernel\Kernel;
final class HttpContext
{
private Kernel $kernel;
private Response $response;
public function __construct(Kernel $kernel)
{
$this->kernel = $kernel;
}
/**
* #When I request :method to :uri
*/
public function iRequest(string $method, string $uri): void
{
$this->request($method, $uri);
}
/**
* #Then the location header should be :location
*/
public function assertLocationHeader(string $location): void
{
// make your assertion
dd($this->response->headers->get('location'), $location);
}
private function request(string $method, string $uri): void
{
$request = Request::create($uri, $method, [], [], [], [], null);
$this->response = $this->kernel->handle($request);
$this->kernel->terminate($request, $this->response);
}
}
