I can’t read session when I pass from next-auth to nodejs

I have Next.js project where I use next-auth and I use node.js for the server. when user log in system, their session should pass to nodejs like this:

this code is part of […nextAuth].ts

 events: {
    async signIn({ user }: any) {
      const { PASS_SESSION_SERVER } = Operation.Mutations;

      const { data } = await ApolloClient.mutate({
        mutation: PASS_SESSION_SERVER,
        variables: {
          sessionUser: {
            id: user.id,
            email: user.email,
            name: user.name,
          },
        },
      });
    },
  },

after I receive the session I store on the Redis successfully like that:

consider that this function is the mutation

getSession: async (_: any, args: any, { prisma, req }: GraphqlContext) => {
      const { sessionUser } = args;

      try {
        const user = req.session.user;
        if (!sessionUser || user) return false;

        req.session.user = sessionUser;

        console.log("[getSession Mutation] ============================= ");
        console.log(req.session);

        return true;
      } catch (error) {
        throw error;
      }
    },

and when I try to access session to get user data I receive only cookie options:

Session {
  cookie: {
    path: '/',
    _expires: 2023-12-10T03:58:52.157Z,
    originalMaxAge: 604800000,
    httpOnly: false,
    secure: false
  }
}

but the interesting fact is that when I do everything from the "Apollo server tool", everything works fine and I get the session without any extra problems.

I think the problem is that when I pass a session from client-side to server-side.

so I need your help
