Laravel API returns Invalid JSON

In routes/api.php I have created following route

Route::get('/config', function(){
    return response()->json([
        'cdn' => cdn_url(),
        'slide_image_path' => '/uploads/front-slides/',
        'offer_image_path' => '/uploads/offers/',
        'offer_image_thumb_path' => '/uploads/offers/thumbs/'
    ]);
});

In browser, I am doing

$.ajax({
    url : 'https://www.example.com/api/config',
    success : function(response){
        var data = JSON.parse(response);
        console.log(data);
    }
});

and getting an error "Unexpected token o in JSON at position 1"; But when I use core php's json_encode() the json response is getting parsed successfully.

Also when I use https://jsonformatter.curiousconcept.com/ to validate JSON It can parse JSON without any issue no matter what I use (json_encode() or response()->json()). But it also gives a warning about invalid JSON.

So far, I have observed that when I use json_encode(), the response contains a header "Content Encoding: gzip". But when I use Laravel's response()->json(), The header Content Encoding: gzip is absent.

I have also tried setting this header manually with header('Content-Encoding: gzip') function while using response()->json(). But then browser gives error "net::ERR_CONTENT_DECODING_FAILED";

I think its an issue related to content encoding or character encoding.

It doens't seem to be anything wrong in your response. The problem is when you are receiving/parsing the data.

Try to use the stringify method:

$.ajax({
    url : 'https://www.example.com/api/config',
    success : function(response){
        var data = JSON.parse(JSON.stringify(response));
        console.log(data);
    }
});
