Accessing User Session with NextAuth in Application Router API Route

Utilizing NextAuth in conjunction with Next.js's App Router, I have established an API route within my /app/api directory. Despite my efforts, I am encountering difficulties retrieving the session associated with the incoming request.

Below is the snippet of my API route, invoked using the get(url) method:

export async function GET(req: NextApiRequest) {
    const session = await getServerSession(req);

    console.log(session);

    return NextResponse.json({ error: "Unauthorized" }, { status: 401 });
}

Upon executing the code above, the server yields the following error message:

[next-auth][error][JWT_SESSION_ERROR] 
https://next-auth.js.org/errors#jwt_session_error Invalid Compact JWE {
  message: 'Invalid Compact JWE',
  stack: 'JWEInvalid: Invalid Compact JWE\n' +
    '    at compactDecrypt (webpack-internal:///(rsc)/./node_modules/jose/dist/node/cjs/jwe/compact/decrypt.js:18:15)\n' +
    '    at jwtDecrypt (webpack-internal:///(rsc)/./node_modules/jose/dist/node/cjs/jwt/decrypt.js:10:61)\n' +
    '    at Object.decode (webpack-internal:///(rsc)/./node_modules/next-auth/jwt/index.js:44:52)\n' +
    '    at async Object.session (webpack-internal:///(rsc)/./node_modules/next-auth/core/routes/session.js:25:34)\n' +
    '    at async AuthHandler (webpack-internal:///(rsc)/./node_modules/next-auth/core/index.js:161:37)\n' +
    '    at async getServerSession (webpack-internal:///(rsc)/./node_modules/next-auth/next/index.js:126:21)\n' +
    '    at async GET (webpack-internal:///(rsc)/./app/api/newwatchlist/route.ts:11:21)\n' +
    '    at async D:\\Coding Projects\\market-pulse\\node_modules\\next\\dist\\compiled\\next-server\\app-route.runtime.dev.js:6:61856',
  name: 'JWEInvalid'
}

The value of session is subsequently null.

Regrettably, I lack access to a response object required for the typical

getServerSession(req, res, authOptions)

method.

In this scenario, how can I retrieve the session linked to the HTTP request within Next's new API routes?

Important note: My setup involves using the MongoDB adapter.

Update: I also experimented with introducing res: NextApiResponse as a parameter, followed by attempting to fetch the session using

const session = await getServerSession(req, res, authOptions);

. Nevertheless, this led to an error

TypeError: res.getHeader is not a function

.

Answer №1

After some trial and error, it became clear that all I needed to do was pass authOptions in my function, without including res or req:

const session = await getServerSession(authOptions);

So, the revised version of my function ended up looking like this:

export async function FETCH(data: NextApiRequest) {
    const session = await getServerSession(authOptions);
    console.log(session);
    return NextResponse.json({ error: "Unauthorized" }, { status: 401 });
}

To begin, ensure that you pass the authOptions into the getServerSession(authOptions) function when working with API Routes.

For the Server Component: Remember to include the Cookie in the request headers when fetching data, as the server component lacks access to browser cookies.

import { headers } from 'next/headers';

const getUser = async () => {
  const res = await fetch(`http://localhost:3000/api/users/me`, {
    headers: headers()
  });
  return res.json();
};

For the Client Component: The cookie is automatically included in the request.

const getUser = async () => {
  const res = await fetch(`http://localhost:3000/api/users/me`);
  return res.json();
};

It appears that the jwt related information was not passed to the getServerSession function.

// Make sure to include authOptions when calling getServerSession
const session = await getServerSession(req, res, authOptions)
