Bulk Partial Update using Nest

Hello, this code works on NEST version="2.4.1"

            var descriptor = new BulkDescriptor();

            foreach (var item in updateList)
            {
                descriptor.Update<VendorProductSearchModel, PartialVendorProductStoreListUpdate>(a => a.Id(item.VendorProductId).Doc(item.PartialUpdate));
            }

            var resp = _client.Bulk(descriptor);
