ErrorException Undefined offset: 0 in Laravel API

In my Laravel-8 application, I have this api as json:

api/tracking/{TrackerID}?sub-key=jkkmkf

which looks like:

api/tracking/19SB22?sub-key=jkkmkf

It is a GET request

When I tried to consume it as shown below, I got this error:

ErrorException Undefined offset: 0

and it points to this line:

$current = $json[0];

How do I resolve this?

Thanks

public function index() {
    $request = Request::create('/api/tracking', 'GET');
    $response = Route::dispatch($request);
    $information = $response->content();
    $json = json_decode($information, true);
    $current = $json[0];
    $geo = explode(',', $json[0]['current_asset_position_coord']);
    return view('welcome', [
        'current' => $current,
        'json' => $json,
        'geo' => $geo
    ]);
}

It means that the array ($json) doensn't contains value with 0 key, your json_decode returns you an empty array.

To make requests to external API's please have a look at Guzzle

use GuzzleHttp\Client;


$client = new Client();
$res = $client->get('https://example.com/api/tracking/19SB22', ['sub-key' => 'jkkmkf']);
echo $res->getStatusCode(); // 200
$json = $res->getBody()->getContents();
