How to use cf-nodejs-client to control the start and stop of hana cloud

[aiddren]

dear support team

We use cf-nodejs-client to control the start and stop of hana cloud db, but an error occurred.
How can I fix this error? Does cf-nodejs-client have the feature of controlling hana cloud db?

source code:
"use-strict";
const cron = require("node-cron");
const endpoint = "https://api.cf.jp10.hana.ondemand.com";
const username = "XXXXX";
const password = "XXXXX";

const CloudController = new (require("cf-nodejs-client")).CloudController(endpoint);
const UsersUAA = new (require("cf-nodejs-client")).UsersUAA;
const ServiceInstances = new (require("cf-nodejs-client")).ServiceInstances(endpoint);

controlTarget(ServiceInstances, "stop", name, id);

function controlTarget(target, operation, name, id) {
CloudController.getInfo().then((result) => {
UsersUAA.setEndPoint(result.authorization_endpoint);
return UsersUAA.login(username, password);
}).then((result) => {
target.setToken(result);
return target.stop(id);
}).then((result) => {
console.log(result);
}).catch((reason) => {
console.log("[catch block]: " + reason);
});
};

error:
[catch block]: {
