Route doesn't show on map for custom DirectionRoute

Nobody has claimed this yet.

I am creating custom DirectionRoute object and passing it to NavigationMapRoute by using :

navigationMapRoute!!.addRoute(currentRoute)

But it doesn't show the route on map. Is there any error handler which we can implement to figure out what causing issue and which specific parameter is wrong?

**Android API:**

**Mapbox Navigation SDK version:**
implementation ('com.mapbox.mapboxsdk:mapbox-android-navigation-ui:0.40.0')

### Steps to trigger behavior

1. Creating custom DirectionRoute object like this :

DirectionsRoute.builder()
.distance(route.totalDistance.toDouble())
.duration(route.totalDuration.toDouble())
.geometry(route.overviewPolyline.rawPointList)
.weightName("routability")
.voiceLanguage("en-US")
.legs(buildLeg(route.legList))
.weight(0.0)
.routeOptions(RouteOptions.builder().baseUrl("https://api.mapbox.com")
.user("mapbox")
.profile("driving-traffic")
.accessToken("pk.-------------MY KEY----------")
.requestUuid("ckg0fffmi00495xpauhg885pm")
.geometries(DirectionsCriteria.GEOMETRY_POLYLINE6)
.coordinates(pointList)
.continueStraight(true)
.roundaboutExits(true)
.overview(DirectionsCriteria.OVERVIEW_FULL)
.steps(true)
.voiceInstructions(true)
.bannerInstructions(true)
.voiceUnits("metric")
.language("en")
.annotations("congestion,distance")
.build())
.build()

2. Passing this custom DirectionRoute object to NavigationMapRoute :

navigationMapRoute!!.addRoute(currentRoute)

3. It doesn't show route on map. Is there any listener which will tell us the problem?

### Expected behavior
Display route on map

### Actual behavior
Route doesn't show

Start at NavigationMapRoute.addRoute and inspect how SDK 0.40.0 consumes the custom DirectionsRoute built in the issue. Compare the supplied geometry, legs, and route options with the route data expected by that entry point, then look for any available error reporting. Done means identifying the invalid or missing input and making the route display on the map.
