The Response’s withJson() fix is NOT working now, it return an empty response with status 200 OK ( on POST request).  
( I’m using the same code i used with 3.5.0, and it was OK):

return $response-\>withJson($resp, 200);

- $resp is an Array…

Is there something new we need to use?

Thanks.

I have the same problem but only when using multiple Middlewares.

A -\> B -\> C -\> B -\> A

If I try to use “return $response-\>withJson($result, 200);” from B or C the response body will be empty.

My code works fine against Slim v3.5 and breaks at v3.6

Might it be because of this?

I’ve just wanted to update from 3.5.0 to 3.7.0 and am experiencing the same behaviour (also with 3.6.0). Going back to 3.5.0 everything works fine again.

@tflight As no one got back here, could you please give a little explenation. I am not that code savvy. By the way I use php7.1.1 if that matters.

@panic, @ChristianDube

Can you give a minimal example? I can’t reproduce getting an empty response using `withJson`.

Hi @llvdl,

don’t know where to begin. Here is a code example and the middlewares:

```
use PDO;
use Psr\Log\LoggerInterface;
use Psr\Http\Message\ServerRequestInterface as Request;
use Psr\Http\Message\ResponseInterface as Response;

class getItems {
	protected $logger;
	protected $db;
	protected $csrf;

	//Constructor
	public function __construct($csrf, PDO $db, LoggerInterface $logger) {
		$this->db = $db;
		$this->logger = $logger;
		$this->csrf = $csrf;
	}

	/**
	 * Returns all items from the database.
	 */
	public function index(Request $request, Response $response, $args) {
		$result = $this->db->query('SELECT * FROM items')->fetchAll(PDO::FETCH_ASSOC);
		$response->withJson($result, 200);
	}

```

Middleware:

```
class Middleware
{
    protected $container;

    public function __construct($container)
    {
        $this->container = $container;
    }
}

```

AuthMiddleware:

```
use Dflydev\FigCookies\FigResponseCookies;

class AuthMiddleware extends Middleware
{
    public function __invoke($request, $response, $next)
    {
        if (!$this->container->auth->isValid()) {
            $this->container->flash->addMessage('error', 'Please sign in before doing that.');

            $settings = $this->container->get('settings');
            $domain = $settings['jwt']['domain'];
            // Expire cookie
            $response = FigResponseCookies::expire($response, 'token', $domain, '/');
            return $response->withRedirect($this->container->router->pathFor('auth.login'));
        }

        $response = $next($request, $response);
        return $response;
    }
}

```

CsrfMiddleware:

```
class CsrfViewMiddleware extends Middleware
{
    public function __invoke($request, $response, $next)
    {
        $this->container->view->getEnvironment()->addGlobal('csrf', [
            'field' => '
                <input type="hidden" name="' . $this->container->csrf->getTokenNameKey() . '" value="' . $this->container->csrf->getTokenName() . '">
                <input type="hidden" name="' . $this->container->csrf->getTokenValueKey() . '" value="' . $this->container->csrf->getTokenValue() . '">
            ',
        ]);

        $response = $next($request, $response);
        return $response;
    }
}

```

GuestMiddleware:

```
class GuestMiddleware extends Middleware
{
    public function __invoke($request, $response, $next)
    {
        if ($this->container->auth->isValid()) {
            return $response->withRedirect($this->container->router->pathFor('home'));
        }

        $response = $next($request, $response);
        return $response;
    }
}
```

I’ve also noticed the response has a content type of “text/html; charset=UTF-8” instead of json.  
With 3.5 I’ve also have a content type of text/html but it works…

This happens when you don’t return the `$response` that you created via `withJson`.

i.e.

```auto
$app->get('/users', function ($request, $response) {
    $response->withJson(['user1'. 'user2']);
});

```

Will not return the JSON:

```auto
$ curl -i http:/localhost:8888/users
HTTP/1.1 200 OK
Host: localhost:8888
Connection: close
X-Powered-By: PHP/7.0.15
Content-Type: text/html; charset=UTF-8

$

```

However:

```auto
$app->get('/users', function ($request, $response) {
    return $response->withJson(['user1'. 'user2']);
});

```

will work:

```auto
$ curl -i http:/localhost:8888/users
HTTP/1.1 200 OK
Host: localhost:8888
Connection: close
X-Powered-By: PHP/7.0.15
Content-Type: application/json;charset=utf-8

["user1","user2"]

```

This is because PSR-7 is immutable and you get back a new Response object. As @tflight noted, there was a bug in earlier versions of Slim3 where it happened to work by accident if you didn’t return the `$response` object as we just modified the underlying stream.

The problem is here:

```auto
	public function index(Request $request, Response $response, $args) {
		$result = $this->db->query('SELECT * FROM items')->fetchAll(PDO::FETCH_ASSOC);
		$response->withJson($result, 200);
	}

```

You do not return the newly created Response that has the JSON in it.

Change to:

```auto
	public function index(Request $request, Response $response, $args) {
		$result = $this->db->query('SELECT * FROM items')->fetchAll(PDO::FETCH_ASSOC);
		return $response->withJson($result, 200);
	}

```

Oh boy… Thank you @akrabat!
