Error workflow doesn't start

Hello! I’ve tried to create same workflow as described in this article: https://medium.com/n8n-io/creating-error-workflows-in-n8n-6e03c9ecbc0f

But the “Error Workflow” doesn’t start. I have picture like this

Here is my code of the “Error workflow”

  {
    "parameters": {},
    "name": "Start",
    "type": "n8n-nodes-base.start",
    "typeVersion": 1,
    "position": [
      250,
      100
    ]
  },
  {
    "parameters": {},
    "name": "Error Trigger",
    "type": "n8n-nodes-base.errorTrigger",
    "typeVersion": 1,
    "position": [
      250,
      300
    ],
    "alwaysOutputData": false
  },
  {
    "parameters": {
      "chatId": "<My chat id>",
      "text": "=An error has occurred in {{$node[\"Error Trigger\"].json[\"workflow\"][\"name\"]}}\nNode: {{$node[\"Error Trigger\"].json[\"execution\"][\"lastNodeExecuted\"]}}\nMessage: {{$node[\"Error Trigger\"].json[\"execution\"][\"error\"][\"message\"]}}\nStack Trace: {{$node[\"Error Trigger\"].json[\"execution\"][\"error\"][\"stack\"]}}",
      "additionalFields": {}
    },
    "name": "Telegram",
    "type": "n8n-nodes-base.telegram",
    "typeVersion": 1,
    "position": [
      450,
      300
    ],
    "credentials": {
      "telegramApi": "MyMonitoringBot"
    }
  }
],
"connections": {
  "Error Trigger": {
    "main": [
      [
        {
          "node": "Telegram",
          "type": "main",
          "index": 0
        }
      ]
    ]
  }
},

Could you tell me what I do wrong?

Welcome to the community @ilyoz!

Did you also specifically set it as Error Workflow to be used on the workflow with the name test5?

No, I didn’t. My bad. I didn’t see it in the article. Thank you for help @jan! Now it works perfectly!

P.S. I put a screenshot for those who will have the same question

Great thanks a lot! Have fun!
