Undefined in console on GET request in NodeJS - node.js

Question

I'm creating a script which is going to automatically receive data from API and store it in MongoDB at specific UTC time.
I use Node-Schedule for scheduling a task at specific time.
CoinMarketCap API for receiving a real time data.
Problem: I receive an undefined in console every second(since the node-schedule is configured to call the code every second). I was looking for any syntax errors or errors in API and wasn't successful. I understand that I receive undefined cause the function doesn't return anything.
Currently doesn't have any ideas what wrong with it at all.
All API keys and DB username password was correct I checked it as well.
Goal: To have the script which is automatically receives data from API and stores it MongoDB collection.
Full Code
const { MongoClient } = require('mongodb');
const schedule = require('node-schedule');
var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
const saveToDatabase = function(BTCdata) {
const url = 'mongodb+srv://name:password#cluster0-1kunr.mongodb.net/<dbname>?retryWrites=true&w=majority';
MongoClient.connect(url, { useNewUrlParser: true, useUnifiedTopology: true }, (err, db) => {
if (err) throw err;
const dbo = db.db('Crypto');
const myobj = { Name: 'BTC', Volume: 'BTCdata' };
dbo.collection('Crypto-Values').insertOne(myobj, (error, res) => {
if (error) throw error;
console.log('1 document inserted');
db.close();
});
});
};
function request(method, url) {
return new Promise(((resolve, reject) => {
const xhr = new XMLHttpRequest();
xhr.open(method, url);
xhr.onload = resolve;
xhr.onerror = reject;
xhr.send();
}));
}
const j = schedule.scheduleJob('* * * * * *', () => {
request(
'GET',
'http://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest?CMC_PRO_API_KEY=API-KEY-HERE',
)
.then((r1) => {
const x1 = JSON.parse(r1.target.responseText);
const BTCdata = x1.data.find((d) => d.symbol === 'BTC').quote.USD.volume_24h; // creating a variable to store a BTC request from API
console.log(BTCdata);
// Saving to database
saveToDatabase(BTCdata);
})
.catch((err) => {
console.log(err);
});
});
EDIT1:
This is a console log of x1 value.
EDIT2:
Was missing this part -
var request = require('request');
After it was added I start receiving a new error in my console which is :
events.js:287
throw er; // Unhandled 'error' event
^
Error: Invalid URI "GET"
at Request.init
at new Request
at request
at Job.job
at Job.Invoke
at Users/path to node modules/node-schedule
at Timeout.onTimeout
EDIT3:
After correction to the code with #Sureshprajapati answer.
New error appears - TypeError: Cannot read property 'responseText' of undefined
Trying to find solution by myself. Still looking for any advice. Thank you.
var requestPromise = require('request-promise');
requestPromise.get({
uri: 'http://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest?CMC_PRO_API_KEY=API-KEY-HERE',
json: true
}).then(r1 => {
const x1 = JSON.parse(r1.target.responseText);
const BTCdata = x1.data.find(d => d.symbol === 'BTC').quote.USD
.volume_24h; // creating a variable to store a BTC request from API
console.log(BTCdata);
// Saving to database
saveToDatabase(BTCdata);
}).catch(err => {
console.log(err);
});

request supports both streaming and callback interfaces natively. If you'd like request to return a Promise instead, you can use an alternative interface wrapper for request. These wrappers can be useful if you prefer to work with Promises, or if you'd like to use async/await in ES2017.
request-promise (uses Bluebird Promises)
This module is installed via npm:
npm install --save request
npm install --save request-promise
Coming to modifying your code as per documentation:
var requestPromise = require('request-promise');
requestPromise.get({
uri: 'http://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest?CMC_PRO_API_KEY=API-KEY-HERE',
json: true
}).then(x1 => {
const BTCdata = x1.data.find(d => d.symbol === 'BTC').quote.USD
.volume_24h; // creating a variable to store a BTC request from API
console.log(BTCdata);
// Saving to database
saveToDatabase(BTCdata);
}).catch(err => {
console.log(err);
});
