Description
The main SNS message handler incorrectly assumes that every message that was parsed using json.loads() without throwing an exception is of dict type, and then uses dict methods like .get() on the parsed object which eventually leads to a crash. In our case this has prevented us from sending a list of dicts, but there's more examples. This PR fixes it by handling the AttributeError exception
