I added ponzu-server in upstart, but I start ponzu-server have some error.
sudo service ponzu-server start
Job for ponzu-server.service failed because the control process exited with error code. See "systemctl status ponzu-server.service" and "journalctl -xe" for details.
journalctl -xe:

This is commonly caused by not assigning the $VARIABLES in the init script that is provided as an example in the Ponzu project.
Make sure you add your own project directory path and other variables before you try to start a daemon/service.
