As it says ASINList not found
You need to add these line of code after below line
$request->setSellerId(MERCHANT_ID);
Code needs to add:
$request->setMarketplaceId($marketplace_id);
$asin_list = new MarketplaceWebServiceProducts_Model_ASINListType();
$asins = array("ASIN1","ASIN2","ASIN3");
$asin_list->setASIN($asins);
$request->setASINList($asin_list);
