Anyone knows why I keep getting following error message?

The message says it, and your SIP message proves it: the SIP message has no body.

nathelper operates on the SDP body, it mangles them (together with rtpproxy) so that the SDP body sent to the receiver contains the address of your machine running OpenSER instead of the real phone. This is so that the machine can act as RTP proxy on network edges.

Since your SIP message has no SDP body there is nothing nathelper can do :-) C'ya, Marc
