Keywordstats returns AuthorizationException

[merkushin]

I try to get data from keywordstats endpoint.

When I call this endpoint without params, then I get empty data array. And I catch error, when I pass concrete date (like in my example below). Both behaviours I consider as wrong. This ad took part in split test, which finished on 1 September 2018.

Here is the error: PHP Fatal error: Uncaught FacebookAds\Http\Exception\AuthorizationException: An access token is required to request this resource.

Here is full example (without secrets):

<?php
declare(strict_types=1);

/**
 * composer.json:
 * {
 *   "require": {
 *     "php": "^7.0",
 *     "facebook/graph-sdk" : "~5.0",
 *     "facebook/php-ads-sdk": "3.1.*"
 *   }
 * }
 */

require_once __DIR__ . '/vendor/autoload.php';

use FacebookAds\Api;
use FacebookAds\Logger\CurlLogger;

$token = '<here-is-token-with-ads-management>';

$api = Api::init(
    '<here-is-app-id>', 
    '<here-is-app-secret>',
    $token
);
$api->setLogger(new CurlLogger());

$response = $api->call("/23842919165120405/keywordstats?date=2018-08-31");
echo 'Ad 23842919165120405 keywordstats on date:' . PHP_EOL;
echo $response->getBody();
echo PHP_EOL . PHP_EOL;

And this is output of this script (w/o secrets):

/usr/local/Cellar/php/7.2.4_1/bin/php /Users/merkushin/dev/app/splittest/facebook-example.php

Process finished with exit code 255

You'll get empty data if you would run curl example. But we get AuthorizationException while using SDK. (And empty data itself is wrong response.)

This will be fix in next release.
