I think by default wwJsonSerializer passes an empty string (e.g. "') and Salesforce expects null. (I'm not sure if that's salesforce-wide or if it's just the instance I am working with.) I modified that section of WriteDate in wwJsonSerializer.prg so that it returns [null] instead of [""].

Are you able to do 2-way synchronization in real-time or do you create a temporary "Update" file on both ends?
