Insufficient Permission when trying to create a folder on Google Drive via API(v3)

Question

I am trying to create a folder on my Google Drive via the API. I am using Node, and have created a script that fetches a daily report and would like to via the API, create

Answer 1

I think that your script works. So can you confirm the following points again?

1. About the scope.
   • At Quickstart, the default scope is var SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly'];. But in order to use drive.files.create, https://www.googleapis.com/auth/drive is required to be added to the scopes.
   • If you modified the scope, please remove the file of drive-nodejs-quickstart.json. And run the script. By this, the authorization is run and the added scopes are reflected to the refresh token and access token.
2. About the version of googleapis
   • Recently, it is reported that there are some bugs for googleapis of v27.0.0, v26.0.1 and v25.0.0. So please confirm your version just in case. I use v24.0.0.
3. Whether Drive API was enabled at API console.
   • About this, I think that from your question, you may have already enabled it.

If these were not useful for you, I'm sorry.

fs.readFile('client_secret.json', function processClientSecrets(err, content) {

    console.log('Error loading client secret file: ' + err);
    return;
  }

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