Google Maps API (JS) Create a route using PlaceId in waypoints

Question

The route create only if I use LatLng or String params but I need create it by PlaceId but it doesn't work

example:

directionsService.route({
        origin: {'placeId': 'ChIJc1lGdwfP20YR3lGOMZD-GTM'},
        destination: {'placeId': 'ChIJdTGhqsbP20YR6DZ2QMPnJk0'},
        waypoints: [{stopover: true, location: new google.maps.Place('ChIJRVj1dgPP20YRBWB4A_sUx_Q')}],
        optimizeWaypoints: true,
        travelMode: google.maps.TravelMode.DRIVING
    }

Answer 1

Just need to pass the google.maps.Place object as the waypoint location. For example:

directionsService.route({
    origin: { placeId: "ChIJc1lGdwfP20YR3lGOMZD-GTM" },
    destination: { placeId: "ChIJdTGhqsbP20YR6DZ2QMPnJk0" },
    waypoints: [{ stopover: true, location: { placeId: "ChIJRVj1dgPP20YRBWB4A_sUx_Q" } }],
    optimizeWaypoints: true,
    travelMode: google.maps.TravelMode.DRIVING
}

location specifies the location of the waypoint, as a LatLng, as a google.maps.Place object or as a String which will be geocoded.

Answer 2

I get a javascript error with the posted code: Uncaught TypeError: google.maps.Place is not a constructor on this line:

waypoints: [{stopover: true, location: new google.maps.Place('ChIJRVj1dgPP20YRBWB4A_sUx_Q')}],

You need to specify that location the same way you do with the origin and destination placeIds:

waypoints: [{
  stopover: true,
  location: {'placeId':"ChIJRVj1dgPP20YRBWB4A_sUx_Q"}
}],

Description in the documentation :

Google.maps.Place object specification

placeId | Type: string The place ID of the place (such as a business or point of interest). The place ID is a unique identifier of a place in the Google Maps database. Note that the placeId is the most accurate way of identifying a place. If possible, you should specify the placeId rather than a placeQuery. A place ID can be retrieved from any request to the Places API, such as a TextSearch. Place IDs can also be retrieved from requests to the Geocoding API. For more information, see the overview of place IDs .
