Error 'Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup' on API call

Question

Trying to make my expressJS app control users' google drive files. I've been utilizing the node 'googleapis' package. After following a slightly dated/incorrect article here, I've gotten the script to:

redirect a user to their authorization url
grab the 'code' from get parameter and then...
register it back as access tokens, which can then be used to...
create a registered 'auth' object

When I use this to create the drive object and try to get it to list files, I get the following error: 'Error: Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup'

This error has already popped up on SO question, and on github.

Following general advice, I re-enabled the drive api, re-downloaded access key. I've also tried replacing the sensitive drive scope a gmail scope, but that didn't work either. I'm not sure where else turn to start debugging at this point. I have a sneaking suspicion my entire auth object is being formed incorrectly but I can't find anything wrong.

This is the related piece of Express app code I'm using to create the authObject and then read drive files.

/**
 * Google Utility class that packages different actions related to authentication
 */
class GoogleUtil {
  constructor(secretFileName = 'client_secret.json') {
    const secret = JSON.parse(fs.readFileSync(secretFileName)).web;
    const { client_id, client_secret, redirect_uris } = secret;
    this.client_id = client_id;
    this.client_secret = client_secret;
    this.redirect_uri = redirect_uris[0];
    this.standardScope = [
      'https://www.googleapis.com/auth/drive',
      // 'https://www.googleapis.com/auth/gmail.readonly',
      // 'https://www.googleapis.com/auth/userinfo.profile'
    ];
  }

  createConnection() {
    return new google.auth.OAuth2(this.client_id, this.client_secret, this.redirect_uri); // form authObject
  }
  getConnectionUrl(auth) {
    return auth.generateAuthUrl({
      access_type: 'offline',
      prompt: 'consent',
      scope: this.standardScope
    });
  }
  async getAccessTokenFromCode(code) {
    var auth = this.createConnection();
    const data = await auth.getToken(code);
    return data.tokens;

  }
}
const g = new GoogleUtil();


/**
 * BEGIN ROUTE DEFINITIONS
 */

// THIS IS FIRST STEP. FRONTEND WILL REDIRECT TO GIVEN URL
app.get('/api/googleLoginUrl', async (req, res) => {
  const oAuth2Client = g.createConnection();
  const url = g.getConnectionUrl(oAuth2Client);
  res.json({ url });
});


// *****
// NOTE: THIS IS ROUTE THAT ATTEMPTS TO LIST FILES AND THROWS ERROR
// *****
app.get('/google-auth-redirect', async (req, res) => {
  if (!req.query.code) return res.send('Malformed request');

  const tokens = await g.getAccessTokenFromCode(req.query.code);
  const auth = g.createConnection().setCredentials(tokens);


  const drive = google.drive({ version: 'v3', auth: auth });
  drive.files.list({
    pageSize: 10,
    fields: 'nextPageToken, files(id, name)',
  }, (err, resp) => {
    if (err) return console.log('The API returned an error: ' + err);
    console.log(resp);
  });

  res.redirect('/');
});

In the google developer console, clicking on 'create credentials' in the drive API overview informs me that my current credentials are compatible. The project scopes do include ' ../auth/drive'.

I'd want it to be able to list files from an authenticated user's account.

I think this might be related to how you are asking for permissions. If you are using your application to manipulate user's drive files you need a couple of things:

Check you have the correct access scopes setup.
Check you authentication parameter/Oauth screen is setup with said scopes.

You might want to read some documentation regarding authorizing users

Hope this helps! ;)
