Why command line tool is not launched for chatting

from one terminal, I ran ~/duckling$ stack exec duckling-example-exe no port specified, defaulting to port 8000 Listening on

on the other terminal, I ran following commands which suppose to launch the command line tool to chat with the chatbot. But it just terminated. Do you have any clue? Thanks.
