Getting ServiceResponseStatus.ZeroResults on DistanceMatrixService().GetResponse

[martinezjm]

Can someone help me? My application was working fine, then all of a sudden I started getting ServiceResponseStatus.ZeroResults from the API call DistanceMatrixService().GetResponse. Is there a maximum call on the API? When does it reset?

Thank you.

Here is the code:

    private MapResponse GetTime(Waypoint startPoint, Waypoint endPoint)
    {
        try
        {
            SortedList<int, Waypoint> origin = new SortedList<int, Waypoint>();
            SortedList<int, Waypoint> destination = new SortedList<int, Waypoint>();

            origin.Add(0, startPoint);
            destination.Add(0, endPoint);

            DistanceMatrixRequest distanceRequest = new DistanceMatrixRequest()
            {
                Units = Units.imperial,
                WaypointsOrigin = origin,
                WaypointsDestination = destination,
                Sensor = false

            };

            DistanceMatrixResponse response = new DistanceMatrixService().GetResponse(distanceRequest);

            var mr = new MapResponse(); //Custom class to hold values

if (response.Rows[0].Elements[0].Status.Equals(ServiceResponseStatus.ZeroResults)) mr.Miles = 0; else {

                mr.Duration = response.Rows[0].Elements[0].duration.Text;
                mr.Miles = Convert.ToInt32(response.Rows[0].Elements[0].distance.Text);
                mr.TotalSeconds = Convert.ToInt32(response.Rows[0].Elements[0].duration.Value);

            }

            return mr;
        }
        catch (Exception ex)
        {
            throw new Exception("GetTime(): " + ex.Message);
        }

I only know of a rate limiter by Google that limits calls to something like 20 per minute over a 15 minute period for anonymous api calls, without setting a key into the signing areas of the library.

Dont quote me on that but realistically you should be seeing OVER_RATE_LIMIT response if that were the case.
