If you see the "AirtableError Unknown field name" error message, or can't find the newest fields or tables to use in your extensions/automations, your base might be out of sync.
To sync your base again, use the Refresh Base button in the options menu of your extension/automation. You can find the Options menu next to the extension/automation name.
💡 After refreshing the base, please refresh your browser windows and try again. That should resolve the issue.
