Index was outside the bounds of the array exception with WcfProxy

[tomrb]

When making a WCF REST Web Service call in our QA environment we are getting the following exception. We cannot replicate this bug in our DEV environment.

This sounds like one of a couple things.

First, maybe it could be that the production server hasn't been configured to allow IIS, ASP.NET, and WCF to support max upload/download data sizes. This is discussed in the Using CSLA 4 book.

Second, and probably more likely, it sounds like the server is returning some HTML instead of the expected byte stream.

DataPortal.Fetch failed (Index was outside the bounds of the array.) ---> System.IndexOutOfRangeException: Index was outside the bounds of the array.

This happens usually because of a security issue. The easiest way to see what's happening is if you can put fiddler on the connection to see what is coming back from the server.
