Small typo: it's "encoder object", not "objective" :) 
What you want there is to put the ID of a "Encoder Definition" (there's
 different choices if you search for "Encoder Definition" in the block
list.

GNU Radio comes with an example for all these! It's called
fecapi_encoders.grc and typically can be found in
/usr/[local/]share/gnuradio/examples/fec ; not quite sure where it gets
installed under OS X, but I think you'll be able to find that file on
your computer :)

Don't use the "packet encoder" block *at all*. It is deprecated!!! It
simply doesn't work reliably, and drops data occasionally (this has
bitten myself).

You'll find a much nicer example in
/usr/[local/]share/gnuradio/examples/digital/packet/packet_loopback_hie
r.grc
