 * Hi,
 * WCFM is giving an Internal Server Error at checkout when on PHP 8.
 * Here’s the bug:
 *     ```
       Uncaught TypeError: array_key_exists(): Argument #2 ($array) must be of type array,
       Stripe\\Util\\CaseInsensitiveArray given in /......../plugins/wc-multivendor-marketplace/includes/Stripe/lib/ApiRequestor.php:402
       ```
   
 * Works with PHP 7.4
    Fails with PHP 8.0
 * Please can you check. Thanks.

 * WCFM not yet fully compatible with PHP 8, please use older version for now.
