Express session id not saving in cookie (graphql) - express

Question

I cannot for the life of this program figure out why this cookie isn't being saved in the browser. If I run the graphql playground (which is on port 4000, the same as the server), the session ID will be stored in the browser no problem. I have cors enabled so this shouldn't be blocking this. But if I send the login request from any other url, it won't save it in the browser. I have tried multiple browsers and it won't save on any of them and I've tried logging the sessions to make sure I am actually saving them. Any ideas?
