I can't delete nor initialize selected cookies

Question

Hi I'm trying to delete selected cookies drom the website I'm working on but for some reason they aren't deleted

That's what I tried to do:

var cookiesList = ["amp_c480ca","_gat","_gcl_au","_gid","_ga","_hjSessionUser_2101300"];
var path = "/";
var domain = ".pic-time.com";
var i = 0;
var name = cookiesList[i];

cookiesList.forEach(deleteSelectedCookie);

function deleteSelectedCookie() {
if(get_cookie(name) ) {
document.cookie = name + "=" +
    ((path) ? ";path="+path:"")+
    ((domain)?";domain="+domain:"") +
    ";expires=Thu, 01 Jan 1970 00:00:01 GMT";
}
name = cookiesList[i++];
}


function get_cookie(name){
    return document.cookie.split(';').some(c => {
        return c.trim().startsWith(name + '=');
    }); 
}

But for some I reason it doesn't initialize/delete the cookies
