HI @tech_voyager
Welcome to community.
This looks like a connection issue. Please test another Google node (e.g., Watch or Get) to confirm the connection. Since you’re self-hosting n8n, setup can be a bit tricky—please double-check that your Google credentials are configured correctly and that all required OAuth scopes are enabled.
