I have added a custom option in product from the back-end.

After that when I tried to update the product programmatically but Facing an issue: When I edited the product all the custom options of product has been deleted.

It removes all options while editing a product. I have checked all entries in the database that's also get deleted.

Finally I found the solution of this.
Not great solution but it's working fine for me.

I have first getting all options of the product before save.

protected function getProductOptions($productObj)

    {

        $objectManager = MagentoFrameworkAppObjectManager::getInstance();

        $customOptions = $objectManager->get('MagentoCatalogModelProductOption')->getProductOptionCollection($productObj);



        $options = ;

        if($customOptions->count() > 0) {

            foreach($customOptions as $customOption) {



                $optionsValue = ;

                $customOptionValues = $objectManager->get('MagentoCatalogModelProductOptionValue')->getValuesCollection($customOption);

                if($customOptionValues->count() > 0) {

                    foreach($customOptionValues as $customOptionValue) {

                        $optionsValue = array(

                            'record_id' => $customOptionValue->getRecordId(),

                            'title' => $customOptionValue->getTitle(),

                            'price' => $customOptionValue->getPrice(),

                            'price_type' => $customOptionValue->getPriceType(),

                            'sort_order' => $customOptionValue->getSortOrder(),

                            'sku' => $customOptionValue->getSku(),

                            'is_delete' => 0,

                        );                

                    }

                }





                $sku = $customOption->getSku();

                $title = $customOption->getTitle();

                $type = $customOption->getType();

                $price = $customOption->getPrice();

                $price_type = $customOption->getPriceType();

                $record_id = $customOption->getRecordId();



                $options = array(

                    'sort_order' => $customOption->getSortOrder(),

                    'title' => $title,

                    'price_type' => $price_type,

                    'price' => $price,

                    'type' => $type,

                    'values' => $optionsValue,

                    'is_require' => 1,

                );



            }

        }



        return $options;        

    }

After that I have added that all options after save the product.

protected function addProductCustomOptions($product, $productOption) 

    {

        $objectManager = MagentoFrameworkAppObjectManager::getInstance();



        $product->setHasOptions(1);

        $product->setCanSaveCustomOptions(true);

        foreach ($productOption as $arrayOption) {

            $option = $objectManager->create('MagentoCatalogModelProductOption')

                    ->setProductId($product->getId())

                    ->setStoreId($product->getStoreId())

                    ->addData($arrayOption);

            $option->save();

            $product->addOption($option);

        }



    }

Now I am getting my all product options same as before.

i am getting this issue in my magento 1 project , can you please suggest any solution ?
