Hello i want implementing wordpress rest api in my nodejs express app.i am using JWT Authentication for WP-API plug in .but i cant not get all users from myapi call. following error i am facing when a call the route:

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

Code for my rest wp route is following:

var WPAPI = require('wpapi'); var wp = new WPAPI({ endpoint: 'domain.com/wp-json' }); wp.myCustomResource = wp.registerRoute('jwt-auth/v1', '/token',
{ methods: 'POST', params: ['username', 'password'] })

.username('myUserName').password('myPassword')
.then(res => console.log(res))
.catch(err => console.error(err))
