    The error OAuth2 token is caused by expired tokens in Google Integration. Please check your Google integration like the Google Drive or Google Spreadsheet and re-integrate to solve the problem.

    You can follow the guide below.

    1. Click on the "integrations" icon

    2. Select your Google Spreadsheet/Google Drive integration, then remove it.

    3. Follow this guide in order to re-integrate your form with Google spreadsheet. For Google Drive here's the guide.

    I hope that helps. Do let us know if you need more information on this.

    Thank you.
