registerRoute doesnt work

[webface]

I am testing against a headless wordpress app using https://ca.wordpress.org/plugins/jwt-authentication-for-wp-rest-api/ V1

I can test the plugin with postman and axios in react but cant get it to work here

var WPAPI = require("wpapi");
var wp = new WPAPI({ endpoint: "http://localhost:1038/wp-json" });

wp.login = wp.registerRoute("jwt-auth/v1", "/token", {
	methods: "post",
	params: ["username", "password"],
});

// wp.posts()
//   .then(data => console.log(data)) // this works
//   .catch(e => console.log);

wp.login()
	.username("admin")
	.password("password")
	.then((res) => console.log(res))
	.catch((err) => console.error(err));

Getting

{
  code: 'rest_no_route',
  message: 'No route was found matching the URL and request method',
  data: { status: 404 }
}
