How to create session on backend?

[vmstukalov]

Hi,

"next": "15.1.6"
"next-auth": "5.0.0-beta.25"

How can I create session on backend. I want to make something similar with Magic Links.

Idea: user should go to the one-time link to signIn, then redirected to dashboard.

I try to set cookies directly to backend, but getting error JWTSessionError. I can't create valid JWT.

let sessionToken  //how can I create valid token?

const nextCookies = await cookies();
    nextCookies.set("authjs.session-token", sessionToken, {
        httpOnly: true,
        secure: process.env.NODE_ENV === "production",
        path: "/",
        maxAge: 60 * 60 * 24 * 365, // 1 year
    });

How can I create session on backend?

Thanks!
