php - Facebook Marketing Api - running on loop throws "AuthorizationException An unknown error has occurred." (on 2nd time)

Question

I'm using Facebook Ads SDK and trying to add users to a custom audience list. As there is a 10000 data limit at a time, for future proof I am trying to add data in a loop.

However, when it hits the second time, it throws an error.

1.

public function test($audienceId, $data)
    Api::init($appId, $appSecret, $token);

    $audience = new CustomAudience($audienceId);

    $schema = [
       CustomAudienceMultikeySchemaFields::EMAIL,
       CustomAudienceMultikeySchemaFields::PHONE,
       //...
    ];

    foreach (array_chunk($data, 500) as $chunk) {
        $audience->addUsersMultiKey($chunk, $schema, true);
    }
}

// And run as

$class = new FbTestClass();
$class->test($audienceId, $data);

If the addUsersMultiKey() runs 1 time, it works perfectly, however if it runs 2 times, it throws an error

FacebookAds\Http\Exception\AuthorizationException - An unknown error has occurred.

2 Then I tried to move App:init() part to __construct(), but the issue persists.

public function __construct() {
   Api::init($appId, $appSecret, $token);
}

public function test($audienceId) {
   $audience = new CustomAudience($audienceId);

   $schema = [
       CustomAudienceMultikeySchemaFields::EMAIL, //...
   ];

   $audience->addUsersMultiKey($chunk, $schema, true);
}

// And run as:

$class = new FbTestClass();

foreach (array_chunk($data, 500) as $chunk) {
   $class->test($audienceId, $chunk);
}

3. I tried looping outside of the test() function, and keeping App::init() inside the test() function, so App::init() gets called multiple times. Still same issue.

This answers says to do the requests individually but how is it possible to do that? But, didn't I try all possible scenarios?

The error seems to be with batched requests - The solution for us was to change the code to do the requests individually.

I believe it's about the runtime because when I refresh, it works alright; so I don't think it's throttling issue (I also tried to sleep(10), in fact it works on refresh).

How can I overcome this issue?

• Maybe there is a way to destroy App instance? Or is there a way to create a new App instance to overwrite previous one?

• I saw a batch request in the facebook docs but couldn't figure out how to use it with my use-case (custom audience & addUsersMultiKey()).

Update: 4 I also tried same thing with graph-sdk

$fb = new Facebook([
      'app_id' => env("FB_APP_ID"),
      'app_secret' => env("FB_APP_SECRET"),
      'default_graph_version' => 'v6.0',
      'default_access_token' => env("FB_ACCESS_TOKEN")
]);

foreach ($chunks as $chunk) {
      $payload = [
          'schema' => $schema,
          'data' => $chunk->toArray()
      ];
      
      $requests[] = $fb->request("POST", "/$customAudienceId/users", ['payload' => $payload]);
}

$batchResponse = $fb->sendBatchRequest($requests);

Here, response array has both request. 1st one is successful, second one same issue.

$batchResponse contains:

responses: array:2 [▼
    0 => Facebook\FacebookResponse ▼
        body => // successful data returned...
    1 => Facebook\FacebookResponse ▼
        body => "{"error":{"message":"An unknown error has occurred.","type":"OAuthException","code":1,"fbtrace_id":"A5...464cGc22gi28Kb"}}"

Answer 1

我发现了这个错误，它实际上是我的结果。

当我进行分块时，我的块索引保留了实际数组的索引，并且由于它没有给出 [0,1,2]，因此导致 api 调用失败。

array_values($chunk);应该解决这个问题。

对于 Laravel 的收藏$chunk->values()->toArray();
