n8n-debug-node

A plug-and-play DEBUG Code node for n8n that shows the real, runtime item-reference syntax ($item(X).json.*, etc.) for all your workflow data fields—no more relying on sometimes-misleading “green/red” UI highlights.

---

✨ Why Use This?

• Copy exact reference syntax: Reveals the real $item(...) field paths you need, as n8n actually resolves them during execution.
• Save time: Eliminates trial-and-error when the UI’s “green/red” dot highlights are wrong or ambiguous.
• Fully standalone: No changes needed upstream, just plug in and debug.

---

🚀 Quick Start

1. Download n8n-debug-node.json from this repo.
2. Import into your n8n (Workflows > Import > File).
3. Open workflow, copy the DEBUG-node, and paste it into any workflow.
4. Connect DEBUG-node after any node and Execute—you’ll see all available runtime item paths.

🛠️ What It Outputs

For each incoming item, you get:

{
  "DEBUG-INFO-Item-0": {
    "json": [
      "$item(0).json.name",
      "$item(0).json.data.id"
    ],
    "binary": [
      "$item(0).binary.file"
    ],
    "miscellaneous-or-other": [
      "$item(0).pairedItem"
    ]
  }
}

Just copy & paste the paths as needed!

👩‍💻 Use Cases

• Quickly copy the correct item syntax for the Expression Editor.
• Debug how Merge, Split, or other advanced nodes shape your data.
• Avoid wasted time and broken workflows due to misleading UI syntax clues.

FAQ

Does this modify my data?
No, it summarizes paths and passes data through unchanged.

Can I use it anywhere?
Yes—simply paste after any node whose outputs you want to inspect.
