// Try adding credentials: 'include' to your fetch call, like so:
// The reason it works when you manually access the address is because HTTP requests made
// by the browser send cookies in the header by default. Fetch doesn't.
// Like for this guy https://stackoverflow.com/questions/67970252/req-cookies-is-object-null-prototype-on-express-router
