mapsplugin / ionic-googlemaps-quickdemo-v5 Goto Github PK

Hi,
I'm fairly new to native google maps (I've used Maps JavascriptAPI successfuly in the past). I followed the quickdemo-v5 example and managed to get "current device location" and "geocoder" to work but I'm unable to get directions to work as it gives me an error as below when I call the requestDirection() method. Can anyone please help me solve this problem.

ERROR Error: Uncaught (in promise): TypeError: Cannot redefine property: waypoints

I copied and used the code from the quickdemo-v5 example.. snippet below:

requestDirection() {
DirectionsService.route({
origin: this.origin,
destination: this.destination,
travelMode: TravelModeId.DRIVING
}).then((result: DirectionsResult) => {
console.log(JSON.stringify(result, null, 2));
this.bounds = result.routes[0].bounds;

  console.log(this.bounds);

  if (!this.renderer) {
    this.renderer = this.map.addDirectionsRendererSync({
      directions: result,
      panel: 'guide',
      draggable: true
    });
    console.log(this.renderer);
    this.renderer.on(GoogleMapsEvent.DIRECTIONS_CHANGED).subscribe(this.onDirectionChanged.bind(this));
    console.log(this.renderer.on(GoogleMapsEvent.DIRECTIONS_CHANGED).subscribe(this.onDirectionChanged.bind(this)));
  } else {
    this.renderer.setDirections(result);
    console.log(this.renderer.setDirections(result));
  }
});

}

onDirectionChanged() {
const directions: DirectionsResult = this.renderer.getDirections();
this.origin = directions.routes[0].legs[0].start_location;
this.destination = directions.routes[0].legs[0].end_location;
this.bounds = directions.routes[0].bounds;
}

onSplitterDragEnd() {
this.map.animateCamera({
target: this.bounds,
duration: 500
});

}

// Update server with user position
updateDBPosition() {
this.uID = this.authService.userData.uid;
this.updateValues = {
currentPosition: this.userPosition,
// status: 'online',
};
this.userPositionService.update_userPosition(this.uID, this.updateValues);
}
