Struggling with Directions
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);
}
