[Drive] TypeError: authClient.request is not a function

[jurbina1]

I am currently following this tutorial: https://developers.google.com/drive/api/v3/quickstart/nodejs

I didn't change the code and it gives me the following error:

(node:46228) UnhandledPromiseRejectionWarning: TypeError: authClient.request is not a function at Object.createAPIRequest (/Users/.../node_modules/googleapis/build/src/lib/apirequest.js:193:20) at Object.list (/Users/.../node_modules/googleapis/build/src/apis/drive/v3.js:469:33) at listFiles (/Users/.../Desktop/sample1.js:72:15) at oAuth2Client.getToken (/Users/.../Desktop/sample1.js:54:23) at /Users/.../node_modules/google-auth-library/build/src/auth/oauth2client.js:158:46 at process._tickCallback (internal/process/next_tick.js:68:7) (node:46228) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 2) (node:46228) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

I don't really know what's the problem and I tried the tutorial in python (to see if I had the same problem) and it works, but I need to be able to do this in nodejs.

Greetings! Can you share a few things with me?

• The version of node.js you're running
• Your package.json
• The exact code you're trying to run :)

Thanks!

NodeJS version: 10.4.1

I am currently not using a package.json since it didn't say anything in the Quickstart Guide.

Code:

const fs = require('fs');
const readline = require('readline');
const {google} = require('googleapis');

// If modifying these scopes, delete credentials.json.
const SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly'];
const TOKEN_PATH = 'token.json';

// 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 Drive API.
  authorize(JSON.parse(content), listFiles);
});

/**
 * 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) {
  const {client_secret, client_id, redirect_uris} = credentials.installed;
  const oAuth2Client = new google.auth.OAuth2(
      client_id, client_secret, redirect_uris[0]);

  // Check if we have previously stored a token.
  fs.readFile(TOKEN_PATH, (err, token) => {
    if (err) return getAccessToken(oAuth2Client, callback);
    oAuth2Client.setCredentials(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 for the authorized client.
 */
function getAccessToken(oAuth2Client, callback) {
  const authUrl = oAuth2Client.generateAuthUrl({
    access_type: 'offline',
    scope: SCOPES,
  });
  console.log('Authorize this app by visiting this url:', authUrl);
  const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout,
  });
  rl.question('Enter the code from that page here: ', (code) => {
    rl.close();
    const {tokens} = oAuth2Client.getToken(code)
    oAuth2Client.setCredentials(tokens);
    fs.writeFile(TOKEN_PATH, JSON.stringify(tokens), (err) => {
        if (err) console.error(err);
        console.log('Token stored to', TOKEN_PATH);
    });
    callback(oAuth2Client);
    /**oAuth2Client.getToken(code, (err, token) => {
      if (err) return callback(err);
      oAuth2Client.setCredentials(token);
      // Store the token to disk for later program executions
      fs.writeFile(TOKEN_PATH, JSON.stringify(token), (err) => {
        if (err) console.error(err);
        console.log('Token stored to', TOKEN_PATH);
      });
      callback(oAuth2Client);
    });**/
  });
}

/**
 * Lists the names and IDs of up to 10 files.
 * @param {google.auth.OAuth2} auth An authorized OAuth2 client.
 */
function listFiles(auth) {
  const drive = google.drive({version: 'v3', auth});
  drive.files.list({
    pageSize: 10,
    fields: 'nextPageToken, files(id, name)',
  }, (err, res) => {
    if (err) return console.log('The API returned an error: ' + err);
    const files = res.data.files;
    if (files.length) {
      console.log('Files:');
      files.map((file) => {
        console.log(`${file.name} (${file.id})`);
      });
    } else {
      console.log('No files found.');
    }
  });
}

Just to make things easier to debug - can you run:

npm init -y
npm install googleapis

[jurbina1]

Okay. This is package.json

{
  "name": "Desktop",
  "version": "1.0.0",
  "description": "",
  "main": "sample1.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "googleapis": "^32.0.0"
  }
}

I'm having the same problem. Any idea why is this happening?

Same problem here trying to use auth.getClient(). The error seems to indicate an authentication problem, albeit not very well. No clue what exactly caused it though. I switched to JWT auth in order to work around it.

Greetings folks! I need a few more details here. This seems to work on the latest version for me. Can you please verify that:

• You are using the most recent version of the googleapis npm module
• You are not directly installing this module if you're using googleapis

I am going to close this out for now. If you are still having problems, please open a new issue with a copy of your package.json :)
