Answer 1

I know this post is from a while back, but I figured I'd post anyway in the hopes of saving someone else time and headaches.
I was having this same problem and after a lot of debugging it turns out that it happens due to malformed XML.
If you're passing Key values with spaces in them, it will trigger this error.
I solved it by removing all the characters that might give the XML parser trouble.
Hope that helps.
