Looks like some of the fields coming from SNS don't match the names used in the Haskell code. Also MessageAttributes appears to be optional, so it is now a Maybe - this is also why omitNothingFields has also been added to the FromJSON instance. This is untested, I can try it and check it works on Monday.
