The browser was unable to fetch data from your Google Sheets Web App. This is usually caused by one of the following:
Invalid URL: The URL must end in /exec. Make sure it does not end in /dev.
Deployment Settings: In the Google Apps Script script editor, click Deploy > New deployment. Ensure the settings are:
- Execute as: Me (your email) - Who has access: Anyone (not "Anyone with Google Account" or "Only Myself").
Account Multi-login Issue: Google Apps Script URLs sometimes throw CORS redirects if you are logged into multiple Google accounts in the same browser. Open this dashboard in a Private / Incognito window or log out of other accounts to check.
