HTTP request method returns null.

Hi Everyone,

I am receiving a NULL response from the API.

<?php

namespace App\Http\Connectors;

use Illuminate\Http\Client\Response;
use Illuminate\Support\Facades\Http;
use Illuminate\Support\Facades\Log;
use App\Models\BCStore;

class BigCommerceAgent{

  const MAX_TIMEOUT = 30;

  private $agent;
  private $url;
  private $token;
  private $clientId;
  private $bcStore;

  public function __construct(Http $httpClient, BCStore $bcStore){
    $this->agent = $httpClient;
    $this->bcStore = $bcStore;
  }

  public function setStoreHash(string $hash){
    $this->url = "https://api.bigcommerce.com/stores/".$hash."/";
    return $this;
  }

  public function setAccessToken(string $token){
    $this->token = $token;
    return $this;
  }

  public function getOrdersCount(array $query): Response
  {
    return $this->request()->get($this->url . 'v2/orders/count?' . http_build_query($query));
  }

  public function getOrders(array $query): Response
  {
    return $this->request()->get($this->url . 'v2/orders?' . http_build_query($query));
  }

  public function getCartOrderMetafields(string $cartId): Response
  {
    return $this->request()->get($this->url . 'v3/carts/'. $cartId .'/metafields');
  }

  public function getCustomers(array $query): Response
  {
    return $this->request()->get($this->url . 'v3/customers?' . http_build_query($query));
  }

  public function getCustomerGroup(int $id): Response
  {
    return $this->request()->get($this->url . 'v2/customer_groups/' . $id);
  }

  public function getProduct(int $id, array $query): Response
  {
    return $this->request()->get($this->url . 'v3/catalog/products/' . $id. '?' . http_build_query($query));
  }


  protected function request()
  {
    $request = $this->agent::withHeaders([
      'X-Auth-Token' => $this->token,
      'Accept' => 'application/json',
      'Content-Type' => 'application/json'
    ]);
    $request->timeout(self::MAX_TIMEOUT);
    $request->asJson();
    return $request;
  }
}

From my Job file I am calling this function as below.

            $customers = $this->bcAgent->getCustomers([
                "id:in" => $orderRow['customer_id']
            ])->json();

This primary job is to export the orders with the customers from bigcommerce. When exporting from my local, I don't have any problem.

When I run this same on the Digital Ocean server, I am encountering a NULL response from the API. This happens very random.

This is my queue configuration

        'database' => [
            'driver' => 'database',
            'connection' => env('DB_QUEUE_CONNECTION'),
            'table' => env('DB_QUEUE_TABLE', 'jobs'),
            'queue' => env('DB_QUEUE', 'default'),
            'retry_after' => (int) env('DB_QUEUE_RETRY_AFTER', 90),
            'after_commit' => false,
        ],

For running the jobs, I am using supervisor with the below command

php artisan queue:work --timeout=3600

Can anyone suggest what's the possible cause for this. Thanks.
