Cannot connect to JIRA with NodeJS (jira-client)

[Siripong_C]

This is my Node JS code:

const jiraApi = require('jira-client');

var jira = new jiraApi({protocol: 'https',
 host: 'jira.XXXX.global',
 username: 'myUsername',
 password: 'myPassword',
 apiVersion: '2'});

jira.findIssue('myIssueNumber').then(() => {
 console.log(`Status: ${issue.fields.status.name}`
)}).catch((error) => {
 console.log(error)});

I expect to see issue.fields.status.name in my terminal but I encounter Request failed with status code 401.

I am sure my username and password are correct because I can access JIRA application via chrome and I can see the detail of this IssueNumber.

I don't know why I encounter 401 error. Can anyone help me?
