Try mine:

var fs = require('fs');
var readline = require('readline');
var google = require('googleapis');
var googleAuth = require('google-auth-library');

// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/calendar-nodejs-quickstart.json
var SCOPES = ['https://www.googleapis.com/auth/calendar'];
var TOKEN_DIR = (process.env.HOME || process.env.HOMEPATH ||
    process.env.USERPROFILE) + '/.credentials/';
var TOKEN_PATH = TOKEN_DIR + 'calendar-nodejs-quickstart.json';

// Load client secrets from a local file.
fs.readFile('client_secret.json', function processClientSecrets(err, content) {
  if (err) {
    console.log('Error loading client secret file: ' + err);
    return;
  }
  // Authorize a client with the loaded credentials, then call the
  // Google Calendar API.
  authorize(JSON.parse(content), insertEvent);
});
/**
 * Create an OAuth2 client with the given credentials, and then execute the
 * given callback function.
 *
 * @param {Object} credentials The authorization client credentials.
 * @param {function} callback The callback to call with the authorized client.
 */
function authorize(credentials, callback) {
  var clientSecret = credentials.installed.client_secret;
  var clientId = credentials.installed.client_id;
  var redirectUrl = credentials.installed.redirect_uris[0];
  var auth = new googleAuth();
  var oauth2Client = new auth.OAuth2(clientId, clientSecret, redirectUrl);
  // Check if we have previously stored a token.
  fs.readFile(TOKEN_PATH, function(err, token) {
    if (err) {
      getNewToken(oauth2Client, callback);
    } else {
      oauth2Client.credentials = JSON.parse(token);
      callback(oauth2Client);
    }
  });
}
/**
 * Get and store new token after prompting for user authorization, and then
 * execute the given callback with the authorized OAuth2 client.
 *
 * @param {google.auth.OAuth2} oauth2Client The OAuth2 client to get token for.
 * @param {getEventsCallback} callback The callback to call with the authorized
 *     client.
 */
function getNewToken(oauth2Client, callback) {
  var authUrl = oauth2Client.generateAuthUrl({
    access_type: 'offline',
    scope: SCOPES
  });
  console.log('Authorize this app by visiting this url: ', authUrl);
  var rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
  });
  rl.question('Enter the code from that page here: ', function(code) {
    rl.close();
    oauth2Client.getToken(code, function(err, token) {
      if (err) {
        console.log('Error while trying to retrieve access token', err);
        return;
      }
      oauth2Client.credentials = token;
      storeToken(token);
      callback(oauth2Client);
    });
  });
}
/**
 * Store token to disk be used in later program executions.
 *
 * @param {Object} token The token to store to disk.
 */
function storeToken(token) {
  try {
    fs.mkdirSync(TOKEN_DIR);
  } catch (err) {
    if (err.code != 'EEXIST') {
      throw err;
    }
  }
  fs.writeFile(TOKEN_PATH, JSON.stringify(token));
  console.log('Token stored to ' + TOKEN_PATH);
}

function insertEvent(auth) {

var event = {
  'summary': 'This is a test Calendar invite using NodeJS',
  'location': 'Under the Bridge',
  'description': 'I dont ever wanna feel Like I did that day But take me to the place I love Take me all the way',
  'start': {
    'dateTime': '2018-02-25T12:58:05-07:00',
    'timeZone': 'America/Los_Angeles',
  },
  'end': {
    'dateTime': '2018-02-26T06:00:00-07:00',
    'timeZone': 'America/Los_Angeles',
  },
  'recurrence': [
    'RRULE:FREQ=DAILY;COUNT=2'
  ],
  'attendees': [
    {'email': 'rhcp@gmail.com'}

  ],
  'reminders': {
    'useDefault': true
  }
};

var calendar = google.calendar('v3');
calendar.events.insert({
  auth: auth,
  calendarId: 'primary',
  resource: event,
}, function(err, event) {
  if (err) {
    console.log('There was an error contacting the Calendar service: ' + err);
    return;
  }
  console.log('Event created: %s', event.htmlLink);
});

}

Proof the sample Quickstart is working. Events are inserted in my calendar:

Answer 2

I had the same issue. I had a version of the google-auth-library that wasn't compatible with the most recent googleapis version. Check your versions - you might need to upgrade and migrate over your google-auth-library which is why the example above doesnt work for you.

Here's the edits you might have to do if this is your issue: https://github.com/google/google-auth-library-nodejs/releases/tag/v1.0.0

Answer 3

I am currently having the same error as this one, using codes from examples and from @noogui. I found this library working as expected although requires a lot of configuration node-google-calendar.

I also hope Google Calendar API will work soon.

Answer 4

googleapis@24.0.0 and google-auth-library@0.12.0 worked for me
