ibm-watson node-sdk всегда возвращает ошибку 503 service unavailable error для watson assistant v1

Node version 10.16.0

ibm-watson version ^ 5.5.0

Node.js код для подключения к Watson Assistant. Обращено https://cloud.ibm.com/apidocs/assistant/assistant-v1

const AssistantV1 = require('ibm-watson/assistant/v1');
const { BasicAuthenticator } = require('ibm-watson/auth');
const { IamAuthenticator } = require('ibm-watson/auth');

const HttpsProxyAgent = require('https-proxy-agent'); // https Agent
const httpsAgent = new HttpsProxyAgent("my proxy url");

const assistant = new AssistantV1({
    version: '2018-09-20',
    authenticator: new BasicAuthenticator({
        username: 'apikey',
        password: 'my password',
        disableSslVerification: true
    }),
    url: 'https://api.eu-de.assistant.watson.cloud.ibm.com',
    httpsAgent
});

const params = {
    workspaceId: 'my workspace id',
};

assistant.listIntents(params)
    .then(res => {
        console.log(JSON.stringify(res, null, 2));
    })
    .catch(err => {
        console.log(err)
    });

Я всегда получаю следующую ошибку:

Я также пробовал использовать «IamAuthenticator», как показано ниже. но та же ошибка. 

const assistant = new AssistantV1({
    version: '2018-09-20',
    authenticator: new IamAuthenticator({
        apikey: 'my password',
        httpsAgent
    }),
    url: 'https://api.eu-de.assistant.watson.cloud.ibm.com',
    httpsAgent
});

Если я не использую httpsAgent, я получаю ошибку ниже.

Он отлично работает, когда я использую модуль npm watson-developer- cloud, поскольку он устарел, я хочу использовать новый модуль ibm-watson.
