n8n errors / Other
No data found for item-index: "1"
Cause
A downstream node references a previous node with fewer items using legacy $node[] syntax, so index 1+ does not exist in the upstream output.
Fix
Replace $node["NodeName"].json["field"] with $item(0).$node["NodeName"].json["field"] to pin to a specific item, or use $item($itemIndex) to match each iteration. Better, use the modern $("NodeName").item.json.field syntax which handles pairedItem linking automatically.
