I got the results error but it seems working

Tell us what’s happening:
It says,
A request to /api/whoami should return a JSON object with your IP address in the ipaddress key.
A request to /api/whoami should return a JSON object with your preferred language in the language key.
A request to /api/whoami should return a JSON object with your software in the software key.

but my website(https://wyrlv.xyz/api/whoami) is exactly json object.
I’m using Laravel(PHP Framework).
Here is my code:

Route::get('/whoami', function(){
    return response()->json( [
        'ipaddress' => $_SERVER['REMOTE_ADDR'],
        'language' => $_SERVER['HTTP_ACCEPT_LANGUAGE'],
        'software' => $_SERVER['HTTP_USER_AGENT']
    ]);
});
