My advise is to convert your string to a byte array and Encode/Decode it on each side. I get tired of running into strange issues like this in my web services so now EVERY method on my web services take in byte arrays and return byte array. It does not add any time to them, since the web services eventually do this anyway.

See this post for examples net-string-to-byte-array

I am not sure if this will help, but I had a similar error with a service where I wanted to stream data, instead of buffer it. Some may not know, but changing the transfer mode to streaming requires a certain design pattern - otherwise, it will just revert to buffering. So, I followed the design pattern, and ran into the same error. I solved it. Here is the post with my answer:
