// Get the single product
[+] Create the route and test route in the thunderClient


NOTE: FOR IMAGE DESTROY FUNCTIONALITY. we will use ._doc.image because
image will call getter and we will get the file this:
http://localhost/uploads/93747823-387.png
but we are adding this http://localhost manually on destroy functionality. so, we dont want the full address of image so we will use _doc.image it will make the image path to uploads/o374298-3987.png
