create docker service using docker engine API in node.js

Question

I try to create service using docker-engine API and I use its request sample.

what is wrong with it? note: I use Axios, express, and docker swarm. before this problem, I could create containers and stop them, and other things that you can do with docker-engine API. I just wanna create services with one replica. I am trying to create a REStful API for my docker swarm. here is my request sample:
