Cannot fetch redux state from component

I am trying to fetch the redux state (user auth state). I tried to console.log it in the mapStateProps variable but all i get is undefined. I tried doing the same from the reducer and I get the variable properly after I initialize it, but when i pass it to the AuthReducer method I do not get an output at all, or see the state variables in the chrome redux dev-tool.

it seems as if the main function AuthReducer doesnt "see" the state variable.

Console:

AuthReducer.js:41 {isLoggedIn: false, accessToken: 'lalaa', username: '', email: '', exp: ''} (<==== right after initialization and before AuthReducer method)
App.js:50 {AuthReducer: ƒ, RegisterReducer: ƒ} 
App.js:51 undefined

AuthReducer.js:

import AuthTypes from "./AuthTypes"
// import axios from 'axios'

const authState = {
// const authState = {
    isLoggedIn: false, 
    accessToken: "lalaa", 
    username: "", 
    email: "", 
    exp: "", 
    // authorities: ["USER"]
}

// function getAuthState (state = authState) {
//     let token = sessionStorage.getItem('token')
//     let expiration = parseInt(sessionStorage.getItem('exp')) // originaly a string 
//     let loggedIn = sessionStorage.getItem('isLoggedIn')
//     try {       
//         if ( (new Date(expiration)) > new Date() ) {
//             console.log('not expired')
//             axios.defaults.headers.common["Authorization"] = `Bearer ${token}`
//             return {
//                 ...state, 
//                 accessToken: token,
//                 exp: expiration,
//                 isLoggedIn: loggedIn,
//             }
//         }
//         // console.log('in try')
//         return state
//     }
//     catch (error) {
//         console.log('in catch')
//         console.log('there was an error: ' + error)
//         return state
//     }
// }

// authState = getAuthState()
// const newAuthState = getAuthState()
console.log(authState)

const AuthReducer = (state = authState, action) => {
// const AuthReducer = (state = newAuthState, action) => {
    console.log('in reducer method')
    console.log(state)
    
    switch (action.type) {

        case AuthTypes.LOGIN_SUCCESS: {
            return {
                ...state,
                isLoggedIn: action.payload.isLoggedIn,
                accessToken: action.payload.accessToken,
                exp: action.payload.exp,
                // username: action.payload.username,
                // email: action.payload.email,
            }
        }

        case AuthTypes.LOGIN_FAIL: 
            return {
                ...state,
                isLoggedIn: false,
                accessToken: '',
                exp: 0,
                // username: action.payload.username,
                // email: action.payload.email,
            }

        default: return state
    }
}

A little bit of what I eventually want to accomplish (just to make sure the answers here are relevant..): I want to check if a user is logged in so I know there to redirect when running the app. (if logged in and access the /login page, so the user is redirected to the /test page. and the opposite). In AuthReducer.js there is a commented out function that basically fetches data from the local session and applies it to the webapp state.
