ParseException thrown when making getConversationData request to Dialog

[aarora91]

Hi,

I am using the getConversationData method to retrieve conversation history for my dialog. I am quite sure that the date format in my input is correct because I am getting back the expected response, but along with it comes a ParseException as follows:

SEVERE: Error parsing: 2016-03-12 20:31:58

Please let me know how to fix this.
Thanks!
