'Access token is invalid' error in spreadsheet library php

[johnnash03]

I need to upload spreadsheet via google drive in cakephp.I am using google-api-php-client to generate access token and php-google-spreadsheet-client to access the sheets.Code is as follows:

`
function test() {
require_once '../vendors/google-api-php-client-2.1.1/vendor/autoload.php';
$client = new \Google_Client();
$client->setApplicationName("spreadsheet");
$client->setDeveloperKey("//My developerkey");
$client = new Google_Client();
$client->setAuthConfig('client_id.json');
if( !isset($_GET['code']) ) {

    $client->addScope(Google_Service_Drive::DRIVE);
    $client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/test' );
    $auth_url = $client->createAuthUrl();
    header('Location: ' . filter_var($auth_url, FILTER_SANITIZE_URL));
} else {

    $client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/test' );
    $auth_url = $client->createAuthUrl();
    $token = $client->fetchAccessTokenWithAuthCode($_GET['code']);
    $client->setAccessToken($token);

    $serviceRequest = new Google\Spreadsheet\DefaultServiceRequest($token['access_token']);
    Google\Spreadsheet\ServiceRequestFactory::setInstance($serviceRequest);
    $spreadsheetService = new Google\Spreadsheet\SpreadsheetService();
    $spreadsheetFeed = $spreadsheetService->getSpreadsheetFeed();
    $spreadsheet = $spreadsheetFeed->getByTitle('Test');
}

`

But I get the error that access token is invalid as shown in following image:

What is it that I am doing wrong?
