Facebook Graph API : empty results when trying to reach leads on LeadgenForms

I'm currently working on an app, with a system user that have access to both Page and AdAccount that I'm querying. I got an access token with all the Permissions that I could query (because I had to try everything I could) :

read_insights, publish_video, catalog_management, pages_manage_instant_articles, pages_show_list, read_page_mailboxes, ads_management, ads_read, business_management, pages_messaging, instagram_basic, instagram_manage_comments, leads_retrieval, whatsapp_business_management, attribution_read, pages_read_engagement, pages_manage_metadata, pages_read_user_content, pages_manage_ads, pages_manage_posts, pages_manage_engagement, public_profile

I am able to get all leadgen_forms, but then when I want to query the leads of these forms, the Facebook API sends me empty data arrays.

The code :

<?php

namespace App\Connecteurs;


use App\Repository\ClientRepository;
use Doctrine\ORM\EntityManagerInterface;
use Facebook\Facebook;

class FacebookGraphConnecteur
{
    const APP_ID       = 'XXXXXXXXXXX';
    const APP_SECRET   = 'XXXXXXXXXXX';
    const ACCESS_TOKEN = 'XXXXXXXXXXXX';

    private $fb;

    private $em;

    public function __construct(EntityManagerInterface $em)
    {
        $this->fb     = new Facebook(
            [
                'app_id'                => self::APP_ID,
                'app_secret'            => self::APP_SECRET,
                'default_access_token'  => self::ACCESS_TOKEN,
            ]
        );
        $this->em     = $em;
    }

    public function recupereLeads()
    {
        $clients_ids = $this->recupereFacebookAdsIdClients();

        foreach ($clients_ids as $client_ids) {
            $token = $this->fb->get("/{$client_ids['facebookAdsId']}?fields=access_token")->getGraphNode()->asArray();
            $response = $this->fb->get("/{$client_ids['facebookAdsId']}/leadgen_forms", $token['access_token']);
            $params['access_token'] = $token['access_token'];
            $forms = $response->getDecodedBody()["data"];
            $leads = [];
            foreach ($forms as $form) {
                if ($form["status"] === "ACTIVE") {
                    $formId = $form['id'];

                    $leadsForm = $this->fb->get("/{$formId}/leads?fields=created_time,id,ad_id,form_id,field_data", self::ACCESS_TOKEN);
                    $leads[] = $leadsForm->getDecodedBody()["data"];
                }
            }
            var_dump($leads);
        }

    }

    private function recupereFacebookAdsIdClients()
    {
        $em = $this->em;
        /** @var ClientRepository $repo */
        $repo = $em->getRepository("App:Client");

        return $repo->recupereFacebookAdsId();
    }
}

The result :

array(16) {
  [0]=>
  array(0) {
  }
  [1]=>
  array(0) {
  }
  [2]=>
  array(0) {
  }
  [3]=>
  array(0) {
  }
  //.... And so on
}

The /<FORM_ID>/leads endpoint give me 200 http code though : enter image description here

I also tryed with the Business SDK, but got the same result :

$leads[] = json_encode((new LeadgenForm($formId))->getLeads(
    $fields,
   $params
)->getResponse()->getContent(), JSON_PRETTY_PRINT);

I also saw that from the v.9.0, we could not get prospect if the app is in development mode (what it is), but I also saw that there were no development / live mod anymore... I'm really confused.

What am I doing wrong ?

Thank you very much for your help !

I'm trying to read all the leads from a leads form using PHP. After some digging I've discovered the following:

According to Facebook Documentation for the marketing API, starting from v9.0, Dev Mode app users can only access leads submitted by someone with a role in that same app.

Blockquote Starting in v9.0, you will not be able to retrieve leads if your app is in Dev Mode. For testing purposes, Dev Mode app users can access leads submitted by someone with a role in that same app. See App Roles. Apps in Live Mode continue to have access to all leads.

Use this tool to add test leads to your app: Lead Ads Testing Tool. After adding a test lead to the form, the data array will return values.

According to the documentation apps in Live Mode continue to have access to all the leads in a form.
