Yes, the new script reference seems to have fixed it. Thanks

Also, it was not hitting the proxy until I added esri.config.defaults.io.alwaysUseProxy = true; so it does not appear that the URL is going over that ~2000 character threshold.

Thanks for the reply. I have added the proxy like you suggested and verified with a breakpoint that the esri JavaScript is going through the proxy, but the JavaScript error is still occuring when I add the 6th stop. Any other ideas?

I am evaluating the ArcGIS JavaScript API online, written a sample app, and have looked through the documentation but cannot find a clear explanation of the max number of stops that can be optimized with time windows using the RouteTask object if I were to pay for the ArcGIS service. What is the max?

When I run the following code it errors saying "Unable to get value of the property 'xhr': object is null or undefined". If I comment out the stop6 variable and only include 5 stops in the request then it works fine and no errors. This is using the sample server, because I'm currently in the process of evaluating this service. Online I've been able to find where there is a limit of 10 stops for the sample server, but not 5 stops.
