How do I use Vimeo oEmbed API in nodejs?

I am working on a react web application that can upload videos to Vimeo and retrieve them when required. I am able to successfully upload the video privately. I am using the hide from Vimeo privacy setting and embed on specific domains option. On uploading the video I want to receive an embeddable iframe string from the backend server so that I can display the video in my react app.
The oEmbed API provided on Vimeo API reference page is working in postman. But when I try to get it through nodejs string I get the following error:

Error: {“error”:”The requested page couldn’t be found.”}

This is my code:

vimeo_embed.js

let Vimeo = require('vimeo').Vimeo;

const USER_ID = "USER_ID"
const USER_SECRET = "USER_SECRET"
const USER_TOKEN = "USER_TOKEN"

let client = new Vimeo(USER_ID, USER_SECRET, USER_TOKEN);

client.request({
    method: 'GET',
    path: '/app/oembed.json/',
    query: {url: 'https%3A//vimeo.com/xxxxxxxx'}
},function (error, body, status_code, headers) {
    if (error) {
      console.log('error');
      console.log(error);
    } else {
      console.log('body');
      console.log(body);
    }
   
    console.log('status code');
    console.log(status_code);
    console.log('headers');
    console.log(headers);
  });

I am not clear about why this error is thrown. I have verified that the authentiction is working.
Please help me.
