New PHP SDK Critical Bug

New PHP SDK Critical Bug

I tried upgrading to the new 2.0.2 PHP CRM SDK, but there's a critical error that makes it impossible to use.

When trying to get a BulkAPIResponse, the code says this:

if (array_key_exists(APIConstants::VARIABLES, $bulkResponseJSON)) {

However, 'APIConstants' does not have anything defined as VARIABLES, which means it always crashes:

 Symfony\Component\Debug\Exception\FatalThrowableError  : Undefined class constant 'VARIABLES'

 at /usr/local/cat/vendor/zohocrm/php-sdk/src/crm/api/response/BulkAPIResponse.php:108
   104|                     array_push($this->bulkEntitiesResponse, new EntityResponse($orgTax));
   105|                 }
   106|             }
   107|         }
 > 108|         if (array_key_exists(APIConstants::VARIABLES, $bulkResponseJSON)) {
   109|
   110|             $variables= $bulkResponseJSON[APIConstants::VARIABLES];
   111|             foreach ($variables as $variable) {
   112|                 if ($variable != null && array_key_exists(APIConstants::STATUS, $variable)) {

 Exception trace:

 1   zcrmsdk\crm\api\response\BulkAPIResponse::processResponseData()
     /usr/local/cat/vendor/zohocrm/php-sdk/src/crm/api/response/CommonAPIResponse.php:78

There doesn't appear to be anywhere to actually report this as a critical, high severity bug - can this be urgently forwarded to the correct people?  (And it's probably worthwhile asking them to enable bug reporting on Github, too)
