Folksonomy engine does not get barcode on some products and can't add properties

[alexgarel]

Alizarine spotted a bug:

I can't add this property to this product: https://world.openfoodfacts.org/product/2000000218021/12-macarons-plaisir-patissier#
I hit "submit" nothing happens :(

It's the json that is sent that is wrong so it's an issue with the JS

{"product": "undefined", "k": "ingredient_list:multiple", "v": "6", "owner": ""}

"product" is wrong

In folksonomy.js, code is retrieved with code = $("#barcode").html();, maybe this value is not available ?

• Please see: Barcode not displayed for products with fake barcodes attributed by OFF, breaks Folksonomy Engine #7267 @alexgarel
• The solution is either:
• to handle Folksonomy Engine server side
• to change the way the FE JS scripts gets the barcode (hidden in the DOM, or from the URL ?)
