Magento Web API giving server internal error add products

Question

I tried posting a product to my Magento site through its REST web API. I am using curl. I got this error:

{"message":"Internal Error. Details are available in Magento log file. Report ID: webapi-5e884238b420f"}

And when I searched for the log file, I found:

/var/www/html/var/log/exception.log:[2020年04月04日 08:15:52] main.CRITICAL: Report ID: webapi-5e884238b420f; Message: Property "ShowDefaultNotificationMessage" does not have accessor method "setShowDefaultNotificationMessage" in class "Magento\CatalogInventory\Api\Data\StockItemInterface". {"exception":"[object] (Exception(code: 0): Report ID: webapi-5e884238b420f; Message: Property \"ShowDefaultNotificationMessage\" does not have accessor method \"setShowDefaultNotificationMessage\" in class \"Magento\\CatalogInventory\\Api\\Data\\StockItemInterface\". at /var/www/html/vendor/magento/framework/Webapi/ErrorProcessor.php:208, LogicException(code: 0): Property \"ShowDefaultNotificationMessage\" does not have accessor method \"setShowDefaultNotificationMessage\" in class \"Magento\\CatalogInventory\\Api\\Data\\StockItemInterface\". at /var/www/html/vendor/magento/framework/Reflection/NameFinder.php:100)"} []

I tried searching for what this error meant. I couldn't find much.

This is my curl request:

curl -X POST "http://167.179.118.154/index.php/rest/default/V1/products" -H "Content-Type:application/json" -H "Authorization: Bearer <token>" -d '{"product":{"id":0,"sku":"string","name":"string","attribute_set_id":0,"price":0,"status":0,"visibility":0,"type_id":"string","created_at":"string","updated_at":"string","weight":0,"extension_attributes":{"website_ids":[0],"category_links":[{"position":0,"category_id":"string","extension_attributes":{}}],"stock_item":{"item_id":0,"product_id":0,"stock_id":0,"qty":0,"is_in_stock":true,"is_qty_decimal":true,"show_default_notification_message":true,"use_config_min_qty":true,"min_qty":0,"use_config_min_sale_qty":0,"min_sale_qty":0,"use_config_max_sale_qty":true,"max_sale_qty":0,"use_config_backorders":true,"backorders":0,"use_config_notify_stock_qty":true,"notify_stock_qty":0,"use_config_qty_increments":true,"qty_increments":0,"use_config_enable_qty_inc":true,"enable_qty_increments":true,"use_config_manage_stock":true,"manage_stock":true,"low_stock_date":"string","is_decimal_divided":true,"stock_status_changed_auto":0,"extension_attributes":{}},"bundle_product_options":[{"option_id":0,"title":"string","required":true,"type":"string","position":0,"sku":"string","product_links":[{"id":"string","sku":"string","option_id":0,"qty":0,"position":0,"is_default":true,"price":0,"price_type":0,"can_change_quantity":0,"extension_attributes":{}}],"extension_attributes":{}}],"configurable_product_options":[{"id":0,"attribute_id":"string","label":"string","position":0,"is_use_default":true,"values":[{"value_index":0,"extension_attributes":{}}],"extension_attributes":{},"product_id":0}],"configurable_product_links":[0],"downloadable_product_links":[{"id":0,"title":"string","sort_order":0,"is_shareable":0,"price":0,"number_of_downloads":0,"link_type":"string","link_file":"string","link_file_content":{"file_data":"string","name":"string","extension_attributes":{}},"link_url":"string","sample_type":"string","sample_file":"string","sample_file_content":{"file_data":"string","name":"string","extension_attributes":{}},"sample_url":"string","extension_attributes":{}}],"downloadable_product_samples":[{"id":0,"title":"string","sort_order":0,"sample_type":"string","sample_file":"string","sample_file_content":{"file_data":"string","name":"string","extension_attributes":{}},"sample_url":"string","extension_attributes":{}}],"giftcard_amounts":[{"attribute_id":0,"website_id":0,"value":0,"website_value":0,"extension_attributes":{}}]},"product_links":[{"sku":"string","link_type":"string","linked_product_sku":"string","linked_product_type":"string","position":0,"extension_attributes":{"qty":0}}],"options":[{"product_sku":"string","option_id":0,"title":"string","type":"string","sort_order":0,"is_require":true,"price":0,"price_type":"string","sku":"string","file_extension":"string","max_characters":0,"image_size_x":0,"image_size_y":0,"values":[{"title":"string","sort_order":0,"price":0,"price_type":"string","sku":"string","option_type_id":0}],"extension_attributes":{"vertex_flex_field":"string"}}],"media_gallery_entries":[{"id":0,"media_type":"string","label":"string","position":0,"disabled":true,"types":["string"],"file":"string","content":{"base64_encoded_data":"string","type":"string","name":"string"},"extension_attributes":{"video_content":{"media_type":"string","video_provider":"string","video_url":"string","video_title":"string","video_description":"string","video_metadata":"string"}}}],"tier_prices":[{"customer_group_id":0,"qty":0,"value":0,"extension_attributes":{"percentage_value":0,"website_id":0}}],"custom_attributes":[{"attribute_code":"string","value":"string"}]},"saveOptions":true}'

Is it because my JSON is holding dummy data (which I just copied from the Magento Web API documentation)? But I tried modifying some of the values like below, and still got the same response:

Answer 1

I think that's the issue of Magento 2, they have patch for this as link https://github.com/magento/magento2/pull/26056

To bypass the issue, you can remove 'show_default_notification_message' of stock_item in body request. Hope this will help you

• forgodsakehold: unfortunately I am still having an error after removing 'show_default_notification_message' ;(;(

Answer 2

Remove this line in your body request.

"show_default_notification_message": true,
