React Native Invalid Token Specified

[unblvdl]

Hi, I'm struggling with jwt-decode in my react native app, whenever I start expo i get Invalid Token Specified error, what am i missing? Here is my code:

var jwt_decode = require('jwt-decode');
import { AsyncStorage } from 'react-native';
const initialState = {
  user: null
};
if (AsyncStorage.getItem('jwtToken')) {
  const decodedToken = jwt_decode(AsyncStorage.getItem('jwtToken'));

  if (decodedToken.exp * 1000 < Date.now()) {
    AsyncStorage.removeItem('jwtToken');
  } else {
    initialState.user = decodedToken;
  }
}

const AuthContext = createContext({
  user: null,
  login: (userData) => {},
  logout: () => {}
});

function authReducer(state, action) {
  switch (action.type) {
    case 'LOGIN':
      return {
        ...state,
        user: action.payload
      };
    case 'LOGOUT':
      return {
        ...state,
        user: null
      };
    default:
      return state;
  }
}

function AuthProvider(props) {
  const [state, dispatch] = useReducer(authReducer, initialState);

  login = async (userData) => {
    try{
      await AsyncStorage.setItem('jwtToken', userData.token);
      dispatch({
      type: 'LOGIN',
      payload: userData
    });
  } catch(e) {
    // save error
  }
  }

  logout = async () => {
    try{
    await AsyncStorage.removeItem('jwtToken');
    dispatch({ type: 'LOGOUT' });
    } catch(e) {
      // save error
    }
  }

  return (
    <AuthContext.Provider
      value={{ user: state.user, login, logout }}
      {...props}
    />
  );
}

export { AuthContext, AuthProvider };`

I had the same issue with keycloak but i realized that the package that i was using had already decoded the token for me. I believe you cant decode the token twice
