Describe the problem/error/question

I am running a self-hosted n8n instance and facing a strange Telegram issue.

Workflow:

Telegram Trigger → AI Agent → OpenAI Chat Model → Telegram Send Message

The Telegram Trigger receives messages correctly and creates executions.

The AI Agent generates output correctly.

The Telegram Send Message node also executes successfully.

What is the error message (if any)?

There is no error.

The Send Message node output returns:

{
  "ok": true,
  "result": {
    "message_id": 1024
  }
}

The output also contains the correct chat ID and message text.

Expected behavior

The bot should send a reply message back to the same Telegram chat.

Actual behavior

  • Telegram Trigger receives messages.
  • Workflow execution succeeds.
  • Send Message returns ok:true.
  • A valid message_id is returned.
  • No reply appears in the Telegram chat.

What I have already checked

  • Verified Telegram Trigger is working.
  • Verified AI Agent output.
  • Verified Send Message text mapping.
  • Verified chat ID mapping.
  • Deactivated and reactivated the workflow.
  • Created new test executions.
  • Telegram API response still returns ok:true.

Environment

  • n8n: Self-hosted
  • Telegram Bot: my_cool_vijay_bot
  • OpenAI Model: gpt-4.1-mini

Screenshots

I will attach:

  1. AI Agent output screenshot
  2. Telegram Send Message node configuration
  3. Send Message node output showing ok:true
  4. Telegram chat screenshot showing no reply
