Using Square Connect PHP SDK, UpsertCatalogObject fatal error - square-connect

Question

I am using the square connect php sdk, and I am getting the following error, and haven't been able to find any solution. I am trying to push a few new categories that have been added on my app (within mysql database).
Building the catelogObject
foreach ($push_array as $key => $cat_name) {
$category = $this->products_lib->get_category($cat_name);
$idempotency_key = uniqid('',true);
$push_obj = new stdClass();
$push_obj->type = 'CATEGORY';
$push_obj->id = '#' . trim($category->name);
$push_obj->category_data = ['name'=>trim($category->name)];
$push_obj->present_at_all_locations = true;
$catelogObject = ["idempotency_key" => $idempotency_key, 'object' => $push_obj];
print_r($catelogObject);
$response = $square_connect->upsert_category($catelogObject);
}
Produces
(
[idempotency_key] => 5996186208eae4.27853833
[object] => stdClass Object
(
[type] => CATEGORY
[id] => #Drinks
[category_data] => Array
(
[name] => Drinks
)
[present_at_all_locations] => 1
)
)
square_connect class
class SquareConnect {
private $access_token = "***********************";
private $sandbox_access_token = "sandbox-*********************";
public function get_locations() {
SquareConnect\Configuration::getDefaultConfiguration()->setAccessToken($this->access_token);
$locations_api = new \SquareConnect\Api\LocationsApi();
echo $locations_api->listLocations();
}
public function get_categories() {
SquareConnect\Configuration::getDefaultConfiguration()->setAccessToken($this->access_token);
$api = new \SquareConnect\Api\CatalogApi();
$retobj = json_decode($api->listCatalog(null, 'CATEGORY'));
// $categories = $retobj->objects;
return $retobj->objects;
}
public function upsert_category($category_object) {
SquareConnect\Configuration::getDefaultConfiguration()->setAccessToken($this->access_token);
$api = new \SquareConnect\Api\CatalogApi();
// return $apiResponse = json_decode($api->UpsertCatalogObject($category_object));
print_r(json_decode($api->UpsertCatalogObject($category_object))) ;
}
public function get_items() {
SquareConnect\Configuration::getDefaultConfiguration()->setAccessToken($this->access_token);
$api = new \SquareConnect\Api\CatalogApi();
echo $api->listCatalog(null, 'ITEM');
}
}
When I run the code, I get the following error :
Fatal error: Access to undeclared static property: stdClass::$swaggerTypes in /vendor/square/connect/lib/ObjectSerializer.php on line 43
Hope that is clear enough, and thanks in advance for assistance

EDIT - Solution: Need to change the object property of $catelogObject to an array not an object as the square connect api documentation instructs
foreach ($push_array as $key => $cat_name) {
$category = $this->products_lib->get_category($cat_name);
$idempotency_key = uniqid('',true);
$push_obj = [];
$push_obj['type'] = 'CATEGORY';
$push_obj['id'] = '#' . trim($category->name);
$push_obj['category_data'] = ['name'=>trim($category->name)];
$push_obj['present_at_all_locations'] = true;
$catelogObject = ["idempotency_key" => $idempotency_key, 'object' => $push_obj];
print_r($catelogObject);
$response = $square_connect->upsert_category($catelogObject);
}
