Google Sheets Error: Invalid Authentication Code

Love Balbooa forms. Trying to Integrate with Google Sheets. I successfully set up the API and oAuth properly per the video instructions. I am able to "Authenticate Google Account" and get an "Authentication Code"

However, when I enter the authentication code, I get the orange error: "Invalid Authentication Code".

I should point out that I also uploaded the google-2.0.zip and unpacked it on my server in components/ba_forms/libraries as suggested in other posts.
