Hi, I am returning a simple array:

`return ['ABC' => 'DEF'];`

which passes through the CoreFunctions, more explicitly `$response->withJson($resp)` .

I am expecting a JSON object returned in the format:

```
{
   "ABC": "DEF"
}

```

But I get nothing back (and the response header is set to `text/html; charset=UTF-8`) .

However, if I run

`return json_encode(['ABC' => 'DEF']);`

then I get the expected outcome.

I thought -\>withJson would do the above, or is this expected behaviour? (I’m running Slim 3.9.2)

I test your case, I get the expected JSON doing:

```
 $app->get('/test/', function (Request $request, Response $response, array $args) {
    $a = ['abc'=>'def'];
    return $response->withJson($a);
});

```

the header is:

`Content-Type:application/json;charset=utf-8`

Thank you @mzc, with your help I managed to pinpoint the issue. I was pushing all requests through a route resolver, and that’s what was causing the unexpected behaviour.

All sorted now, thanks again 😄
