Hello programmers,
can somebody please help me out here ? what could be the cause of this error message:

Uncaught TypeError: Cannot read property 'id' of undefined


here is the code
Code:
var products = [
	{"id": 1, "name": 'Assassin Creed', "category": '', "price": 13.45, "quantity_in_stock": 5},
