必应地图：方向模块DirectionsUpdated事件引发错误。我们找不到一个或多个航点之间的路线

Question

必应地图方向管理器在directionsUpdated事件上引发错误。

当我尝试使用已知的源地址和目标地址纬度＆长地址绘制路线时，它不会在地图上绘制路线，而只是显示源地址和目标图标并引发以下错误。

错误：我们找不到一个或多个航点之间的路线。

下面是LoadDirection方法代码。

Microsoft.Maps.loadModule('Microsoft.Maps.Directions', (e) => {

  this.directionsManager = new Microsoft.Maps.Directions.DirectionsManager(this.detailMap);
  this.directionsManager.clearAll();
  // Set Route Mode to driving
  this.directionsManager.setRequestOptions({
    routeMode: Microsoft.Maps.Directions.RouteMode.driving,
    routeDraggable: false
  });

  this.directionsManager.setRenderOptions({
    drivingPolylineOptions: {
      strokeThickness: 3
    }
  });

  this.directionsManager.setRenderOptions({
    firstWaypointPushpinOptions: { visible: false },
    lastWaypointPushpinOptions: { visible: false },
    waypointPushpinOptions: { visible: false }
  });

  const waypoint1 = new Microsoft.Maps.Directions.Waypoint({
    address: '2115 Beall St, Houston, TX 77008, US',
    location: new Microsoft.Maps.Location(29.8052803, -95.4181495), icon: ''
  });

  const waypoint2 = new Microsoft.Maps.Directions.Waypoint({
    address: '4231 Brightwood Dr, Houston, TX 77068, US',
    location: new Microsoft.Maps.Location(30.00005, -95.50392)
  });

  this.directionsManager.addWaypoint(waypoint1);
  this.directionsManager.addWaypoint(waypoint2);


  // Add event handler to directions manager.
  Microsoft.Maps.Events.addHandler(this.directionsManager, 'directionsUpdated', function (e) {
    console.log(e);
    this.detailPathLayer.clear();

    const routeIndex = e.route[0].routeLegs[0].originalRouteIndex;
    const nextLocation = e.route[0].routePath[routeIndex + 1];
    const pinLocation = pin.getLocation();
    const nextCoord = this.CalculateNextCoord(pinLocation, nextLocation);

  });

  Microsoft.Maps.Events.addHandler(this.directionsManager, 'directionsError', function (e) {
    console.log('Error: ' + e.message + '\r\nResponse Code: ' + e.responseCode);
  });

  this.directionsManager.calculateDirections();

});

在您提供的两个位置之间寻找路线应该没有任何问题。下面的独立代码可以正常工作，并且在控制台上打印了DirectionsUpdated事件arg（请注意，您已经将航点图钉设置为通过渲染选项不可见）：

var map = new Microsoft.Maps.Map(<CREATE_YOUR_MAP>);

Microsoft.Maps.loadModule('Microsoft.Maps.Directions', (e) => {

  this.directionsManager = new Microsoft.Maps.Directions.DirectionsManager(map);
  this.directionsManager.clearAll();
  // Set Route Mode to driving
  this.directionsManager.setRequestOptions({
    routeMode: Microsoft.Maps.Directions.RouteMode.driving,
    routeDraggable: false
  });

  this.directionsManager.setRenderOptions({
    drivingPolylineOptions: { strokeThickness: 3 },
    firstWaypointPushpinOptions: { visible: false },
    lastWaypointPushpinOptions: { visible: false },
    waypointPushpinOptions: { visible: false }
  });

  const waypoint1 = new Microsoft.Maps.Directions.Waypoint({
    address: '2115 Beall St, Houston, TX 77008, US',
    location: new Microsoft.Maps.Location(29.8052803, -95.4181495), icon: ''
  });

  const waypoint2 = new Microsoft.Maps.Directions.Waypoint({
    address: '4231 Brightwood Dr, Houston, TX 77068, US',
    location: new Microsoft.Maps.Location(30.00005, -95.50392)
  });

  this.directionsManager.addWaypoint(waypoint1);
  this.directionsManager.addWaypoint(waypoint2);

  Microsoft.Maps.Events.addHandler(this.directionsManager, 'directionsUpdated', function (e) {
    console.log(e);
  });

  Microsoft.Maps.Events.addHandler(this.directionsManager, 'directionsError', function (e) {
    console.log('Error: ' + e.message + '\r\nResponse Code: ' + e.responseCode);
  });

  this.directionsManager.calculateDirections();
});

您可以检查这两个位置之间是否确实引发了错误吗？一切都发生在DirectionsUpdated处理程序中吗？ （例如CalculateNextCoord？）
