Getting product page moved to new link prestashop 1.7

[beginner1]

Hi, I am trying to get the link of the product pages in prestashop. After going through the product class I found the function getLink() and using that I get a link but when I try to go to that link I get an error that page moved to a new link. How to solve this?

 

$product = new Product("any example product id lets say 4");
$link = $product->getLink();
