What might be the problem? Here is my post request

  router.post("/users", async (req, res) => {
  const user = new User(req.body);
  try {
    await user.save()
    //sendWelcomeEmail(user.email,user.name)
    const token = await user.generateAuthToken()
    res.status(201).send({user:user,token:token});
  } catch (e) {
    res.status(400).send(e);
  }
});

The following is my client postman view for the post request

The collection is created and i can view it in robo3t.The issue is that my post request is returning an empty object as seen in the above image
