Google spreadsheet api Request had insufficient authentication scopes

Question

I\'m making an script to read data from google spreadsheet using the following script on nodejs:

var url = oauth2Client.generateAuthUrl({
    access_type:            


        

Answer 1

1. Firstly delete the credentials files ~/.credentials/sheets.googleapis.com-nodejs-quickstart.json (depending on your setting)

2. Change the scope variable used for reading cells from Google Spreadsheets from

var SCOPES = ['https://www.googleapis.com/auth/spreadsheets.readonly'];

to

var SCOPES = ['https://www.googleapis.com/auth/spreadsheets'];

3. After the execution of code, API will authenticate again and then the issue will be resolved.
