history/activity v3 and datetime

Hi,

I am trying to use /history/activity version 3. When I try to access the get directly, I got status 400 with the error validation.null-not-allowed.from. As I understand from the reference, the from field is optional?

When I try to past in the from field as json in the body, I am still getting the same error. Just wondering if I am missing anything from here.

Thanks in advance.
