Rect-leaflet和Leaflet-Routing-Machine：未捕获的错误：对象作为React子元素无效

如何解决Rect-leaflet和Leaflet-Routing-Machine：未捕获的错误：对象作为React子元素无效

我试图将地图的引用传递给使用Leaflet-Routing-Machine制作的useRef组件。本质上来说，标记工作得很好，并且希望路由出现在point A和point B之间。

但是我的控制台出现此错误：

未捕获的错误：对象作为React子对象无效（找到：object 使用键{options，_router，_plan，_requestCount，_formatter， _itineraryBuilder，_events，_initHooksCalled，_map，_pendingRequest，_container，_altContainer，_leaflet_id}）。如果要渲染子级集合，请改用数组

这是我的地图：

import React,{ useState,useEffect,useRef } from 'react'
import { Map,Marker } from 'react-leaflet';
import LocateControl from '../LocateControl/LocateControl.jsx';
import MapboxLayer from '../MapboxLayer/MapboxLayer.jsx';
import L from "leaflet";
import LCG from 'leaflet-control-geocoder';
import Routing from '../RoutingMachine/RoutingMachine.jsx'

export default function MyMap({getAddressFromLatLong,hillfinderFormButtonRef,setCurrentLocation,setCurrentDestination}) {
  var [zoom,setZoom] = useState(4);
  var [map,setMap] = useState(null);
  var [animate,setAnimate] = useState(false);
  var [draggable,setDraggable] = useState(true);
  var [markerData,setMarkerData] = useState([]);
  var [amountOfMarkers,setAmountOfMarkers] = useState(0);
  var [markerPointsForRouting,setMarkerPointsForRouting] = useState(null)

  useEffect(() => {
    hillfinderFormButtonRef.current = clearMarkers;

    return() => {
     hillfinderFormButtonRef.current = null;
    }
  });

  useEffect(() => {
    if (markerData.length === 2){
      setMarkerPointsForRouting(markerData)
    }
  });

function addMarker(e){
  // setShowMarkers(showMarkers => !showMarkers)
  var coords = e.latlng;
  if (amountOfMarkers < 2) {
    setAmountOfMarkers(amountOfMarkers => amountOfMarkers + 1)
    updateAddressFromMarker(amountOfMarkers,coords);
    setMarkerData(markerData => [...markerData,coords])
  }
  else null;
}

function updateMarker(e){
 console.log("e.target.options ",e.target);
  console.log('markerData in updateMarker func',markerData);
  var markerLatLng = e.target.getLatLng(); //get marker LatLng
  var markerIndex = e.target.options.marker_index;
  updateAddressFromMarker(markerIndex,markerLatLng)

  setMarkerData(markerData => {
   markerData[markerIndex] = markerLatLng;
   return markerData;
  })
}

function updateAddressFromMarker(marker,latLng){
    var geocoder = new L.Control.geocoder();
     geocoder.options.geocoder.reverse(latLng,5,(address)=>{
      getAddressFromLatLong(marker,address[0].name)
    },null)
}

function clearMarkers(){
 console.log("markerData ",markerData);
  setMarkerData(markerData => [],...markerData);
  setAmountOfMarkers(0);
  setCurrentLocation(''),setCurrentDestination('')
}

function toggleAnimate() {
  setAnimate(animate => !animate);
}

  var MAPBOX_ACCESS_TOKEN = process.env.MAPBOX_ACCESS_TOKEN;

  var locateOptions = {
    position: 'topright',strings: {
      title: 'Show me where I am,yo!'
    },onActivate: () => {} // callback before engine starts retrieving locations
  };

    var mapRef = useRef();

    useEffect(()=>{
      var {current = {}} = mapRef;
      var { leafletElement: map } = current;
     setMap(map)
      console.log("leafletElement ",map);
    },[mapRef])

  return (

        <Map animate={animate} zoom={zoom} onClick={addMarker} ref={mapRef}>
        { markerData.map((element,index) => (
            <Marker
              key={index}
              marker_index={index}
              position={element}
              draggable={draggable}
              onDragend={updateMarker}
              icon={index === 0 ? greenIcon : redIcon}
            />
          ))}

          <MapboxLayer
            accessToken={MAPBOX_ACCESS_TOKEN}
            style="mapbox://styles/mapbox/streets-v9"
          />
          <LocateControl options={locateOptions} startDirectly />
 {console.log("map ",map)}

 {console.log("markerPointsForRouting ",markerPointsForRouting)}
           {markerPointsForRouting && <Routing myMapRef={map} latLng={markerPointsForRouting} />}
        </Map>

  )
}

这是我的路由机器组件：

import L from "leaflet";
import "leaflet-routing-machine";
import { withLeaflet } from "react-leaflet";

function Routing({myMapRef,latLng}){
 console.log("latLng ",latLng);

  //  useEffect(() => {

  // }),[startingCoords.lat,startingCoords.lng,endingCoords.lat,endingCoords.lng];

  var startingCoords = {
    lat: latLng[0].lat,lng: latLng[0].lng
  }

 console.log("startingCoords.lat ",startingCoords.lat);
 console.log("startingCoords.lng",startingCoords.lng);

  var endingCoords = {
    lat: latLng[0].lat,lng: latLng[1].lng
  }

  let leafletElement = L.Routing.control({
    waypoints: [L.latLng(startingCoords.lat,startingCoords.lng),L.latLng(endingCoords.lat,endingCoords.lng)]
  }).addTo(myMapRef)

    return leafletElement;
}

export default withLeaflet(Routing);

任何人都可以帮助我，为什么我的地图在Routing组件中的引用未被识别。
