Riposte solution

One of the requested OAuth scopes is invalid or not enabled. Double-check the scopes your application is requesting for Google API access. With Riposte, ensure the default scopes (e.g., Gmail modify) are used or configure only valid scopes. Adjust the scope and re-initiate auth via /auth/sessions.
