Error Trigger activates on workflow failures. Ignore Manual Failures filters out testing runs.\n2. Error details (workflow name, timestamp, error message, failed node) are extracted and inserted into the data table.\n3. Every hour, unemailed errors are retrieved. If >5 errors exist or oldest error >24 hours, report generation starts.\n4. AI summarizes errors with tips, generates HTML table, and emails the complete report.\n\n**Setup steps:**\n- Configure Error Trigger to monitor your workflows\n- Set up Gmail credentials for notifications\n- Configure OpenAI API key\n- Customize data table schema\n- Adjust schedule in Run every hour node" }, "typeVersion": 1 }, { "id": "71ef77a5-6918-41c6-8ff0-37a0883b22b2", "name": "Calculator", "type": "@n8n/n8n-nodes-langchain.toolCalculator", "position": [ 1624, 432 ], "parameters": {}, "typeVersion": 1 }, { "id": "30e8edaf-def4-4a18-821a-b439a095026c", "name": "Sort", "type": "n8n-nodes-base.sort", "position": [ 592, 460 ], "parameters": { "options": {}, "sortFieldsUi": { "sortField": [ { "fieldName": "createdAt" } ] } }, "typeVersion": 1 }, { "id": "eeaba522-a90a-4450-ad29-46dc0c9d66b6", "name": "high error count or been a day1", "type": "n8n-nodes-base.filter", "position": [ 1040, 460 ], "parameters": { "options": {}, "conditions": { "options": { "version": 3, "leftValue": "", "caseSensitive": true, "typeValidation": "strict" }, "combinator": "or", "conditions": [ { "id": "f8de07d3-6fa6-466c-be6d-438aef94a5da", "operator": { "type": "array", "operation": "lengthGt", "rightType": "number" }, "leftValue": "={{ $json.data }}", "rightValue": 5 }, { "id": "5f907458-d775-445b-8517-1461eb84f68c", "operator": { "type": "boolean", "operation": "true", "singleValue": true }, "leftValue": "={{ DateTime.now().diff(DateTime.fromISO($('Sort').first()?.json?.createdAt), 'hours').hours.round() >= 24 }}", "rightValue": "" } ] } }, "typeVersion": 2.3 }, { "id": "a0e8e245-d98c-4832-8138-b0bca4e7f6af", "name": "Run every hour", "type": "n8n-nodes-base.scheduleTrigger", "position": [ 144, 460 ], "parameters": { "rule": { "interval": [ { "field": "hours" } ] } }, "typeVersion": 1.3 }, { "id": "7378503f-bd85-4fdb-9144-a1fcb1354455", "name": "Generate Workflow Errors Table HTML", "type": "n8n-nodes-base.html", "position": [ 1264, 312 ], "parameters": { "html": "=\n\n\n\n \n Workflow Errors\n\n\n \n \n \n \n \n \n \n \n \n \n \n \n {{ $('Aggregate').item.json.data.map((record, index) => {\n const bgColor = index % 2 === 0 ?
