Exception on ReturnDirections Server 10.1

JustinHunter

When I enable ReturnDirections I get the following exception:

[PHP]System.ArgumentException was caught
  Message=Number contains invalid characters.
  Source=ESRI.ArcGIS.Client
  StackTrace:

  InnerException:

I can only assume that the < 0.1 that it returns is causing the error when trying to convert it to a number, but I cannot be certain.

Any ideas? Returning directions is absolutely mandatory.

This may be because it's trying to return a newer representation of the compressed geometry than the your route task knows how to deal with.  The server can return the older format if the output routes don't include Zs or Ms.  Does your network have Zs.  If not, is it trying to return Ms?  You can try explicitly setting the routeTask.outputLines = TRUE_SHAPE so it doesn't return measures.  Is it possible for you to run fiddler or something to intercept what the route service is returning?
