Custom attributes values not updated

[danyvega1990]

When I tried to update a custom attribute from an existing product using the save method in the ProductRepositoryInterface the code don't throw any errors but the attribute remains with the old data.

Preconditions

1. Magento 2.1.8
2. PHP 7.0

Steps to reproduce

• namespace Vendor\Module\Cron;
• use Magento\Catalog\Api\ProductRepositoryInterface;
• use Magento\CatalogInventory\Api\StockRegistryInterface;
• class CronDownloadData
• {

• protected $productRepository;
  

• protected $stockRegistry;

• public function __construct(
  

•     SunskyProductRepositoryInterface $repository,
  

•     DirectoryList $directoryList,
  

•     ProductRepositoryInterface $productRepository,
  

•     StockRegistryInterface $stockRegistry
  

• ) {

•     $this->productRepository = $productRepository;
  

•     $this->stockRegistry = $stockRegistry;
  

• }
  

• public function updateLocalProduct($modelObj){

•     try {
  

•         $local_product = $this->productRepository->get($modelObj->getItem_no());
  

•         $local_product->setCustomAttribute('description', 'Some description');
  

•         $this->productRepository->save($local_product);
  

•     } catch (\Exception $ex){
  

•         // nothing to do this time;
  

•     }
  

• }
  

• }

Expected result

1. The existing product shows the new description.

Actual result

1. Description not update at all

I am having issues with Custom Options in Magento 2.2. When I do an option for Warranty with Values Standard Warranty at a 0 price and extended warranty at 149.99 as a required field with drop down box, it saves, but when I make a change again to the product and save, it triggers an error.

Warning: array_filter() expects parameter 1 to be array, string given in /chroot/home/homedics/svago.com/html/vendor/magento/module-configurable-product/Controller/Adminhtml/Product/Initialization/Helper/Plugin/Configurable.php on line 145

A technical problem with the server created an error. Try again to continue what you were doing. If the problem persists, try again later.
