This is because OnlineMapsDirectionStep.TryParseORS is an obsolete method that does not work anymore because Open Route Service completely changed API.
I think we will need to remove this class, so as not to confuse users, and update the example.
We will do it in the next update.

Use OnlineMapsOpenRouteService.GetDirectionResults to get the result object.
Use OnlineMapsOpenRouteServiceDirectionResult.Route.points to get an array of points.
