Expected Behavior

After allowing the app to access my account via the browser, I can paste the code displayed in the browser into the prompt and be authenticated.

Actual Behavior

After allowing access, pasting the code into the terminal, and pressing enter, an error is returned

Steps to Reproduce the Problem

1. Follow the instructions written at Google Sheets API Docs to setup the project.
2. run ruby quickstart.rb
3. Allow access to the app via the browser
4. paste the auth code from the browser to the terminal. The error is returned at this step.

Specifications

• Ruby version (ruby -v) : Ruby 2.7.1

Changing sheets/quickstart/quickstart.rb:31 to:

  code = gets.strip

fixes the problem and allows me to successfully authenticate the quickstart app.
