I am using expo React Native for developing my app, Redux for state management, ExpressJS for backend, MongoDB as database.

I am trying to fetch logged-in user data, JWT tokens are not saved in cookies. I don't know if cookies work with react native or not? I have tested the API with postman, API is working and also JWT Tokens are saved in cookies when I test it with postman or thunder-client VS Code extension. Here is the code:

Backend:

exports.getUserDetails = catchAsyncErrors(async (req, res, next) => {
  const user = await User.findById(req.user.id);

  if (!user) {
    return next(new ErrorHandler("User not found", 404));
  }

  res.status(200).json({
    success: true,
    user,
  });
});

Redux State:

export const LoadUser = () => async (dispatch) => {
  try {
    dispatch({ type: "LOAD_USER_REQUEST" });
    const { data } = await axios.get(`${API_URL}/api/auth/me`);
    dispatch({
      type: "LOAD_USER_SUCCESS",
      payload: data.user, //Not loading data.
    });
  } catch (error) {
    dispatch({
      type: "LOAD_USER_FAIL",
      payload: error.response.data.message,
    });
  }
};

Frontend App.js file:

import { Provider as RNP_Provider } from "react-native-paper";
import { Provider } from "react-redux";
import Index from "./Index";
import { LoadUser } from "./actions/authAction";
import store from './store'
import { useEffect } from "react";

export default function App() {

  useEffect(() => {
    store.dispatch(LoadUser());
  }, [])

  return (
    <Provider store={store}>
      <RNP_Provider>
        <Index />
      </RNP_Provider>
    </Provider>
  );
}
