Unable to get session in nextauth middleware when deployed to netlify

malfunctioning part of the middleware:

callbacks: {
        async authorized({ token, req }) {
            // Route protection
            const session = await getToken({
                req,
                secret: process.env.NEXTAUTH_SECRET
            })
            const pathname = req.nextUrl.pathname
            const isAuth = !!token

            const notSensitiveRoutes = ['/', '/pricing', '/api/auth/signin', '/api/auth/callback/credentials', '/api/auth/session']

            console.log(token)
            console.log(session)
            console.log(req.cookies)

            if (!isAuth && !notSensitiveRoutes.some((route) => (pathname === route)) && pathname.startsWith('/api')) {
                return false
            } else if (!isAuth && !notSensitiveRoutes.some((route) => (pathname === route))) {
                return false
            }
            return true
        }
    }

Everything works perfect when using netlify dev - token, and session are valid objects containing all information, after deploying getToken returns null and token received as a function argument also is null. Of course after log in. The only difference between the dev and production that I noticed is the cookie name: next-auth.session-token in dev and __Secure-next-auth.session-token in production but I don’t know if it makes any difference.

Also if I add raw: true to get Token:

const session = await getToken({
                req,
                secret: process.env.NEXTAUTH_SECRET,
                raw: true
            })

session is still null

I don’t know if it will be useful but here is netlify site name: https://snazzy-jalebi-fb75cc.netlify.app/
Because of this behavior I can’t access any of the protected routes. Also there are no error messages in functions, edge functions and build logs.

I’ve been googling and debugging for the past 2 days and found nothing so I would really appreciate any help : )

After some further research it turned out that it was indeed a problem with cookie name and changing the code to the following solved the issue.

const session = await getToken({
                req,
                secret: process.env.NEXTAUTH_SECRET,
                cookieName: process.env.NODE_ENV === 'production' ? '__Secure-next-auth.session-token' : 'next-auth.session-token'
            })

I will leave it here in case anyone else encounters this issue. Also if anyone knows a better solution I would appreciate sharing it.

Hi, where do I get this bit of code? I’m using next auth with MUI’s toolpad and don’t have this piece of code in their example project.
