Directions API: Unmarshal error in detecting Route.Legs as type string

[samkim130]

I kept getting the error where I couldn't unmarshal a saved sample data because for some reason it would think Route.Legs is a type of string. I modified the code to test it directly right after getting a response, but still the same issue.

Environment details

1. Specify the API at the beginning of the title (for example, "Places: ...")
2. OS type and version
3. Library version and other environment information

• googlemaps.github.io/maps v1.3.2 (the latest)
• go version go1.16.5 darwin/amd64

Steps to reproduce

1. Get []map.Route from valid client request through the Directions API
2. Marshal the object
3. Unmarshal the same object

Code example

        routes := getSampleRoutes()
        jsonObj, err := json.MarshalIndent(routes, "", "   ")
	if err != nil {
              log.Fatal(err)
        }
        // At this point, I was able to check that the proper data came through and that the object was marshalled properly
	var newRoutes []maps.Route
	err = json.Unmarshal(jsonObj, &newRoutes)
	if err != nil {
              log.Fatal(err) // hits error here
        }

Stack trace

fatal error: json: cannot unmarshal object into Go struct field Route.legs of type string

Can u copy this test case

google-maps-services-go/directions_test.go

Line 69 in 621d707

func TestDirectionsTransit(t *testing.T) {

and paste the JSON string into it

and paste the result here?

As I think it might be related to ur response.
