How it works

  • it will return workflows that have buil-in nodes not of latest version with information of node name, type, current version and latest version for that type

Set up steps:

  • You need to have n8n credentials set, you can get n8n API key under settings
  • set your instance base URL in "instance base url" node

Disclaimar:

Only check build-in nodes, community nodes are not supported

n8n Workflow: Check for Outdated Built-in Nodes

This n8n workflow helps you identify if any built-in nodes within your n8n instance are not running their latest available version. This is crucial for maintaining workflow stability, leveraging new features, and benefiting from bug fixes.

What it does

This workflow performs the following steps:

  1. Manually Trigger: The workflow is initiated manually.
  2. Fetch Node Data: It makes an HTTP request to the n8n API (/nodes) to retrieve a list of all available built-in nodes and their latest versions.
  3. Fetch Workflow Data: It then makes another HTTP request to the n8n API (/workflows) to get a list of all workflows currently deployed on your instance.
  4. Extract Node Information from Workflows: For each workflow, it iterates through its nodes, extracting the name and typeVersion of each node used.
  5. Split Out Workflow Nodes: It splits the aggregated node data from all workflows into individual items for easier processing.
  6. Filter for Built-in Nodes: It filters these nodes to only include those that are built-in (i.e., their name starts with n8n-nodes-base.).
  7. Extract Latest Version Information: For each built-in node found in a workflow, it attempts to find its corresponding latest version from the data fetched in step 2.
  8. Compare Versions: It compares the typeVersion of the node used in the workflow with the nodeVersion of the latest available built-in node.
  9. Identify Outdated Nodes: It uses an If node to branch the flow, identifying which nodes are outdated (i.e., their typeVersion is less than the nodeVersion of the latest).
  10. Aggregate Outdated Nodes: It aggregates all identified outdated nodes into a single list.
  11. Prepare Output: It uses a Code node to format the output, likely to present a clear list of outdated nodes.
  12. Summarize Results: It summarizes the findings, providing a concise overview of the outdated nodes.
  13. Set Output Fields: It sets specific fields for the final output, making it easy to consume.

Prerequisites/Requirements

  • n8n Instance: An active n8n instance where you want to run this check.
  • n8n API Access: The n8n instance must be configured to allow API access, and the HTTP Request nodes will need appropriate authentication (e.g., API Key, Basic Auth) to access the /nodes and /workflows endpoints. This typically involves setting up an n8n API credential.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Credentials:
    • Locate the "HTTP Request" nodes.
    • Ensure they are configured with the correct n8n API URL (e.g., http://localhost:5678/api/v1/nodes and http://localhost:5678/api/v1/workflows).
    • Set up an n8n API credential and select it for both HTTP Request nodes to authenticate your requests.
  3. Execute Workflow: Click "Execute Workflow" in the Manual Trigger node to run the check.
  4. Review Results: Inspect the output of the final nodes (e.g., "Summarize", "Edit Fields") to see a list of any built-in nodes in your workflows that are not running their latest version.

Key settings: Operation: download File ID: ={{ $json.id }} Creds: googleDriveOAuth2Api Output: Binary (default key: data) and original metadata. --- 3) Extract from File Purpose: Extract text from PDF (OCR as needed) for AI parsing. Key settings: Operation: pdf OCR: enable for scanned PDFs (in options) Output: JSON with OCR text at {{ $json.text }}. --- 4) Message a model (AI JSON Extractor) Purpose: Convert OCR text into strict normalized JSON array (invoice schema). Key settings: Node: @n8n/n8n-nodes-langchain.openAi Model: gpt-4.1 (or gpt-4.1-mini) Message role: system (the strict prompt; references {{ $json.text }}) jsonOutput: true Creds: openAiApi Output (per item): $.message.content → the parsed JSON (ensure it’s an array). --- 5) Create or update an account (Salesforce) Purpose: Upsert Buyer as Account using an external ID. Key settings: Resource: account Operation: upsert External Id Field: taxid_c External Id Value: ={{ $json.message.content.buyer.tax_id }} Name: ={{ $json.message.content.buyer.name }} Creds: salesforceOAuth2Api Output: Account record (captures Id) for downstream Opportunity. --- 6) Create an opportunity (Salesforce) Purpose: Create Opportunity linked to the Buyer (Account). Key settings: Resource: opportunity Name: ={{ $('Message a model').item.json.message.content.invoice.code }} Close Date: ={{ $('Message a model').item.json.message.content.invoice.issue_date }} Stage: Closed Won Amount: ={{ $('Message a model').item.json.message.content.summary.grand_total }} AccountId: ={{ $json.id }} (from Upsert Account output) Creds: salesforceOAuth2Api Output: Opportunity Id for OLI creation. --- 7) Build SOQL (Code / JS) Purpose: Collect unique product codes from AI JSON and build a SOQL query for PricebookEntry by Pricebook2Id. Key settings: pricebook2Id (hardcoded in script): e.g., 01sxxxxxxxxxxxxxxx Source lines: $('Message a model').first().json.message.content.products Output: { soql, codes } --- 8) Query PricebookEntries (Salesforce) Purpose: Fetch PricebookEntry.Id for each Product2.ProductCode. Key settings: Resource: search Query: ={{ $json.soql }} Creds: salesforceOAuth2Api Output: Items with Id, Product2.ProductCode (used for mapping). --- 9) Code in JavaScript (Build OLI payloads) Purpose: Join lines with PBE results and Opportunity Id ➜ build OpportunityLineItem payloads. Inputs: OpportunityId: ={{ $('Create an opportunity').first().json.id }} Lines: ={{ $('Message a model').first().json.message.content.products }} PBE rows: from previous node items Output: { body: { allOrNone:false, records:[{ OpportunityLineItem... }] } } Notes: Converts discount_total ➜ per-unit if needed (currently commented for standard pricing). Throws on missing PBE mapping or empty lines. --- 10) Create Opportunity Line Items (HTTP Request) Purpose: Bulk create OLIs via Salesforce Composite API. Key settings: Method: POST URL: https://<your-instance>.my.salesforce.com/services/data/v65.0/composite/sobjects Auth: salesforceOAuth2Api (predefined credential) Body (JSON): ={{ $json.body }} Output: Composite API results (per-record statuses). --- 11) Update File to One Drive Purpose: Archive the original PDF in OneDrive. Key settings: Operation: upload File Name: ={{ $json.name }} Parent Folder ID: onedrive folder id Binary Data: true (from the Download node) Creds: microsoftOneDriveOAuth2Api Output: Uploaded file metadata. --- Data flow (wiring) Google Drive Trigger → Download File From Google Download File From Google → Extract from File → Update File to One Drive Extract from File → Message a model Message a model → Create or update an account Create or update an account → Create an opportunity Create an opportunity → Build SOQL Build SOQL → Query PricebookEntries Query PricebookEntries → Code in JavaScript Code in JavaScript → Create Opportunity Line Items --- Quick setup checklist 🔐 Credentials: Connect Google Drive, OneDrive, Salesforce, OpenAI. 📂 IDs: Drive Folder ID (watch) OneDrive Parent Folder ID (archive) Salesforce Pricebook2Id (in the JS SOQL builder) 🧠 AI Prompt: Use the strict system prompt; jsonOutput = true. 🧾 Field mappings: Buyer tax id/name → Account upsert fields Invoice code/date/amount → Opportunity fields Product name must equal your Product2.ProductCode in SF. ✅ Test: Drop a sample PDF → verify: AI returns array JSON only Account/Opportunity created OLI records created PDF archived to OneDrive --- Notes & best practices If PDFs are scans, enable OCR in Extract from File. If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
