createAsyncThunk function returns userId undefined data attribute

Solution for createAsyncThunk function returns userId undefined data attribute
is Given Below:

I’m trying to fetch appointment data from my rails-api backend using the createAsyncThunk function. When I

console.log('appointmentDate', appointmentDate);
console.log('doctorId', doctorId);
console.log('userId', userId);

After clicking the submit button to create a new appointment; I get:

appointmentDate => 2021-07-30 which is fine
doctorId => 2 which is also fine.
userId => undefined which is not what I'm expecting. I expected a number just like doctorId

I have tested the backend with postman and everything is fine. And since I can’t fetch the correct data. I can’t create an appointment when I submit the form

This is how I’m destructuring the user state before adding it to the postAppointment action creator for dispatch

const { data: userData } = useSelector((state) => state.user);
const { userId } = userData;
since `user_Id` is part of the `user` state in my `store`. I can destructure it as above and add it to my `dispatch`.

And this is how I’m dispatching it inside the NewAppointment component

dispatch(postAppointments({ userId, doctorId, appointmentDate }))
      .then(() => {
        setSuccessful(true);
        alert.show('Appointment created', {
          type: 'success',
          timeout: 2000,
        });
        setLoading(false);
      })
      .catch((error) => {
        console.log(error.message);
        setSuccessful(false);
      });

I don’t know what I’m missing with the user destructuring and dispatching the action creator?

Here are the other codes

    console.log('userId', userId);
    const response = await fetch(`${API}/users/${userId}/appointments`, {
      method: 'POST',
      headers: {

    });
    const data = await response.json();
    console.log('appointmentsData', data);
    if (!response.ok) throw new Error(data.failure);
    localStorage.setItem('token', data.jwt);
    console.log('localstorageData', data);

    return data;
  },
);

          )}
        </form>
      </div>
    </div>
  );
};
export default NewAppointment;

And the API url returns undefined for the userId variable as shown below

POST https://agile-escarpment-87534.herokuapp.com/api/v1/users/undefined/appointments 404 (Not Found)

This is my first project using createAsyncThunk and still trying to understand how it works. I have also checked similar posts, but none solved my issue.
Any support or constructive criticism is welcome.

you will need the token from here

  const { user_id, jwt } = userData;

add the extracted token from the userData to postAppointments

dispatch(postAppointments({ user_id, doctor_id, appointment_date, jwt }))
      .then(() => {
        setSuccessful(true);
        alert.show('Appointment created', {
          type: 'success',
          timeout: 2000,
        });
        setLoading(false);
      })
      .catch((error) => {
        console.log(error.message);
        setSuccessful(false);
      });

finally add the token to the fetch request

export const postAppointments = createAsyncThunk(
  'appointments/postAppointments',
  async (
    {
      user_id, appointment_date, doctor_id, jwt
    },
  ) => {
    console.log('appointmentDate', appointment_date);
    console.log('doctor_id', doctor_id);
    console.log('user_id', user_id);
    const response = await fetch(`${API}/appointments`, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        Accept: 'application/json',
        // this your missing header
        Authorization: `Bearer ${jwt}`
      },

      body: JSON.stringify({
        appointment_date,
        doctor_id,
        user_id,
      }),
    });
    const data = await response.json();
    console.log('appointmentsData', data);
    if (!response.ok) throw new Error(data.failure);
    localStorage.setItem('token', data.jwt);
    console.log('localstorageData', data);

    return data;
  },
);

This is just a guess.. because I don’t have actual code.

UPDATE:

Another way to write that fetch:

fetch(`${API}/appointments`, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    Accept: 'application/json',
    Authorization: `Bearer ${jwt}`
  },
  body: JSON.stringify({
    appointment_date,
    doctor_id,
    user_id,
  }),
}).then(response => {
  response.json();
}).then(data => {
  console.log('Success:', data);
  localStorage.setItem('token', data.jwt);
}).catch((error) => {
  // request just fail
  throw new Error('Error:', error);
});
