Browser is not receiving cookies after deployment

Hi Support team, I deployed my react app on netlify which has backend deployed on My backend uses JWTs saved as cookies as an authentication system. When somone logs in successsfully, they should get cookie in browser. It works fine on local host but after deploying on netlify, my browser does not receive cookies. I’m not sure what the issue is.

This is my back end login controller

This is my front end api request

export async function login(user: Partial): Promise {
try {
const response = await fetch(${root}login, {
method: “POST”,
headers: { “Content-Type”: “application/json” },
body: JSON.stringify(user),
credentials: “include”,
const loggedUser = await response.json();
if (response.ok) {
const { token } = loggedUser;
document.cookie = auth=${token}; path=/; HttpOnly;
return loggedUser;
} catch (error) {

Any help would be greatly appreciated.

Without seeing the site, we’re only left to guess. My guess is that, since you’re not setting the cookie with the domain, browsers are rejecting that because is on the Public Suffix List.
