Cant't get session testing Api calls with jest

[tonyjara]

Hi, I'm trying to test my api's individually like this:

describe('tests', () => {
  initTestDb();
  it('tests', async () => {
    
    const userProfile = await testAccountSignup(mockSignupData);

    const { req, res } = createMocks({
      method: 'POST',
    });
    await createMembershipApi(req, res);

    expect(res._getStatusCode()).toBe(200);
  });
});

And inside my api I have this:

export default async function createMembershipApi(
  req: NextApiRequest,
  res: NextApiResponse
) {
  try {
    cheReqMethod(req, res, 'POST');
    const secret = process.env.NEXTAUTH_SECRET;

    const session = (await getToken({
      req,
      secret,
    })) as { user: UserProfile } | null;
    console.log(session);

    if (!session) return res.status(403).json({ message: 'unauthorized' });
    const { user } = session;

    return res.status(200).json({ user });
  } catch (e: any) {
    logOnDevEnv(e);
    if ('message' in e) {
      return res.status(500).json({ message: e.message });
    }
    return res.status(500).json({ message: 'something went wrong' });
  }
}

However I'm not getting the session from the getToken method. I have looked for an answer but so far I've only come across some implementations involving react-testing-library. My intention is only testing the api's.
If anyone has dealed with this or can point me in the right direction I would really appreciate it.
