REST API set-rolling does not work

[Mudasir Ahmed]

Fixed: I was passing malformed json request. This is not a defect.

Below is the request and response invoking the REST method to rolling update the exhibitor config.
Apparently I am experiencing that the rolling update starts but does not update the Ports and stops rolling. The exhibitor logs do not say much, nor there is any documentation out there.
Any idea what could be the problem?
