Jest e2e tests. Problem with getSession

[pwozniak1986]

Hi.

I'm trying to make e2e test in my app which is using next-auth and prisma.
Most of endpoints utilize next-auth session in following way:

const session = await getSession({ req });
if (!session) {
    return res.status(401).end();
}

To be able to access the session during the tests, before all, the user and session object are created, csrf token is fetched. With csrf token and session token the cookie is created. The cookie is later provided with the NextApiRequest object by node-mocks-http to the endpoint however the next-auth getSession method is not returning a valid session based on this request.

What else has to be inside this request so the getSession returns a valid session?
