React Native render error: null is not an object (evaluating origin.location)（1个答案）
2天前关闭。

import { StyleSheet, Text, View } from 'react-native';
import React from 'react';
import MapView, { Marker } from 'react-native-maps';
import tw from 'tailwind-react-native-classnames';
import { useSelector } from 'react-redux';
import { selectOrigin } from '../slices/navSlice';

const Map = () => {
  const origin = useSelector(selectOrigin);

  return (
    <MapView 
      style={tw`flex-1`}
      mapType="mutedStandard"
      initialRegion={{
        latitude: origin.location.latitude,
        longitude: origin.location.longitude, 
        latitudeDelta: 0.005,
        longitudeDelta: 0.005,
      }}
    />
  );
};

export default Map;

const styles = StyleSheet.create({});;

这是我的代码，我试图创建一个超级克隆，但当我运行它时，我收到以下错误：ERROR TypeError: Cannot read property 'location' of null
下面是我的navSlice.js以供参考。

import { createSlice } from "@reduxjs/toolkit";

const initialState = {
  origin: null, 
  destination: null, 
  travelTimeInformation: null,
};

/* Data Layer*/
export const navSlice = createSlice({
  name: 'nav',
  initialState,
  reducers: {
    setOrigin: (state, action) => {
      state.origin= action.payload;
    },
    setDestination: (state, action) => {
      state.destination= action.payload;
    },
    setTravelTimeInformation: (state, action) => {
      state.travelTimeInformation= action.payload;
    },  
  },
});

export const {
  setOrigin,
  setDestination,
  setTravelTimeInformation
} = navSlice.actions;

// Selectors. Need one for each action

export const selectOrigin = (state) => state.nav.origin;
export const selectDestination = (state) => state.nav.destination;
export const selectTravelTimeInformation = (state) => 
  state.nav.travelTimeInformation;

// Reduce in our store.js file. Initially wrote and now connecting it. 
export default navSlice.reducer;

有人能帮我找出这里可能出了什么问题吗？
我试着看了一下文档，我不确定我会在哪里出错。我也有一个工作参考，我想我检查了相当彻底，但也许没有-任何想法？
