What this workflow does
This AI workflow has 13 nodes and runs on a schedule (every day at 10:00). Along the way it connects Google Sheets, OpenAI Chat Model and Snapshot Site (community).
How it runs
Trigger: On a schedule (every day at 10:00).
- Read Event Sources (Google Sheets): read (sheet)
- Loop Over Event Sources (Loop Over Items (Split in Batches)): loops over the items in batches
- Get Page HTML (Snapshot Site): screenshot
- Check for API Error (If): checks a condition and branches into true / false
- Build Error Record (Edit Fields (Set)): sets 3 fields: url, message, occurredAt
- Clean HTML (Code): runs custom JavaScript code

- Save Events (Google Sheets): append or update (sheet)
Services it uses
Before you upgrade to n8n 3.0
We can't fully verify this one: it relies on 1 community package, and n8n 3.0 turns unverified community packages off by default (N8N_UNVERIFIED_PACKAGES_ENABLED=false).
- Check that n8n-nodes-snapshot-site is verified or supports 3.0 (used in Get Page HTML).
