Needs changes. This template uses 2 thing(s) that n8n 3.0 removes: HTTP Request Tool (legacy), AI Agent v1 (old agent modes). 2 breaking item(s) found. Static check, last run 2026-10-19.

What this workflow does

This AI workflow has 27 nodes and runs when a chat message arrives (plus 3 other triggers). Along the way it connects HTTP Request, Google Gemini Chat Model, Telegram and Gmail. It also calls pve.proxmox.com and 0.0.0.0:8006 over HTTP.

How it runs

Trigger: When a chat message arrives (plus 3 other triggers).

AI Agent: runs an AI agent, with model: Google Gemini Chat Model; 3 tools (Proxmox, Proxmox API Wiki, Proxmox API Documentation); output parser: Auto-fixing Output Parser
Switch: routes items into 6 branches
HTTP Request: calls an HTTP API
If: checks a condition and branches into true / false
If: checks a condition and branches into true / false
Structure Response (Code): runs custom JavaScript code
HTTP Request: calls an HTTP API
HTTP Request: calls an HTTP API
HTTP Request: calls an HTTP API (DELETE)

Before you upgrade to n8n 3.0

2 things in this workflow are removed in n8n 3.0. Fix them before you upgrade:

HTTP Request Tool (legacy) in Proxmox API Documentation, Proxmox, Proxmox API Wiki: replace with HTTP Request node connected to the AI Agent's Tool input.
AI Agent v1 (old agent modes) in AI Agent1 (v1.7), AI Agent (v1.7): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
Also check Gmail Trigger below v1.4 runs as v1.4 (drafts skipped, max emails per poll).

Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).

Removed in 3.0	Replace with
HTTP Request Tool (legacy) Proxmox API Documentation, Proxmox, Proxmox API Wiki	HTTP Request node connected to the AI Agent's Tool input
AI Agent v1 (old agent modes) AI Agent1 (v1.7), AI Agent (v1.7)	Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
