Node.JS Google Slides API TypeError: Cannot read property 'presentations' of undefined

Question

我对 Node.JS 和 Google 幻灯片 API 还很陌生。我一直在使用快速入门并对其进行修改，但一直出现错误：

(node:22396) UnhandledPromiseRejectionWarning: TypeError: Cannot read 
property 'presentations' of undefined

这是我的代码，快速入门中未涉及授权功能，因此不包括在内。

const fs = require('fs');
const readline = require('readline');
const {google} = require('googleapis');
const promise = require('promise');
// If modifying these scopes, delete token.json.
const SCOPES = ['https://www.googleapis.com/auth/presentations.readonly'];
const TOKEN_PATH = 'token.json';

var auth = '000000000000-ithinkthissupposedtobesecret.apps.googleusercontent.com';
    var title = "Cheese";

    // Load client secrets from a local file.
    fs.readFile('credentials.json', (err, content) => {
      if (err) return console.log('Error loading client secret file:', err);
      // Authorize a client with credentials, then call the Google Slides API.
      authorize(JSON.parse(content), createPresentation);
    });
   /**
Authorization from quickstart goes here (https://developers.google.com/slides/quickstart/nodejs)
   */
    function createPresentation(title, auth) {
        const slides = google.slides({version: 'v1', auth});
        return new Promise((resolve, reject) => {
          // [START slides_create_presentation]
          this.slidesService.presentations.create({
            title,
          }, (err, presentation) => {
              if (err) return console.log(err);
            console.log(`Created presentation with ID: ${presentation.presentationId}`);
            // [START_EXCLUDE silent]
            resolve(presentation);
            // [END_EXCLUDE]
          });
          // [END slides_create_presentation]
        });
    }

非常感谢任何帮助，谢谢！

将this.slidesService.presentations.create更改为slides.presentations.create
