I can't set the SameSite attribute of the cookie to None in Nodejs (Express)

I was able to self-resolve and will describe how I was able to solve the problem.In the code there are two sessions and a cookie session, but I decided to use the cookie session as it seems to work fine.The end result is the following

var cookieSession = require("cookie-session");app.set('trust proxy', 1)app.use(    cookieSession({      name: "__session",      keys: ["key1"],        maxAge: 24 * 60 * 60 * 100,        secure: true,        httpOnly: true,        sameSite: 'none'    }));

I think your first solution should be good. Try with lowercase 'none' as well.

try SameSite: 'none' with capital S it worked for me but i used express-session with cookie-parser... i think your code not working because of small s, when i change my to sameSite it's not working for me too, but SameSite works just as expected

also i use npm i cors

here is my piece of code

app.use(session({    key: 'session_cookie_user_auth',    secret: 'mooncore',    store: sessionStore,    resave: false,    saveUninitialized: false,    cookie: {        SameSite: 'none',        maxAge: 1000 * 60 * 60 * 60    }}));
