Sterling Serialization issue - Object of type 'System.Int32' cannot be converted to type 'System.DateTime'

I created a new data model class to store in a Sterling NoSQL database. On the first and all subsequent attempts to save or retrieve data of this type, I received the error message at the bottom of this post. A number of other people reported similar issues. Apparently it is some type of serialization/deserialization issue. I didn’t find a suggested resolution, but on a whim, moved the AssessmentDate DateTime property from the top of the list of properties in the class to the bottom and that seemed to resolve the issue.

Object of type 'System.Int32' cannot be converted to type 'System.DateTime'.
