getSession returning null in next js API only in Get requests

Question

I am trying to make a request (logged in with session), to get the id from the session and to make a request using that ID. But the session is null, when I do a post request the session is okay.

Component

export async function getServerSideProps(context) {
  const res = await axios.get(`${process.env.API_URL}/company/jobs`);
  return {
    props: {
      jobs: res.data.jobs,
    },
  };
}

API Request

import { getSession } from "next-auth/react";

export default async (req, res) => {
  const { method } = req;
  switch (method) {
    case "GET":
      try {
        const session = await getSession({ req });

        console.log(session + " SESSION "); //RETURN NULL

        console.log(JSON.stringify(session));
        const jobs = await prisma.jobs.findMany({
          where:{
            userId: session.id
          }
        });
        return res.status(200).json({ success: true, jobs });
      } catch (error) {
        return res.status(404).json({
          success: false,
          message: error.message,
        });
      }
