+# 📚 SIMPLE: How to Fix Node 7 Data
+
+## 🔍 What's Happening:
+
+**Node 2 creates data:**
+```json
+{
+  "repo_full_name": "gitadmin/test-repo",
+  "commit_sha": "abc123",
+  "task": "Build project...",
+  ...
+}
+```
+
+**Node 7 can't see this data!**
+
+Why? Because **Node 3 (SSH) doesn't pass the data through**.
+
+## ✅ SOLUTION: Check What Node 7 Actually Receives
+
+### Step 1: Debug First
+In Node 7, replace ALL code with:
+```javascript
+return $json;
+```
+
+This will show you exactly what data Node 7 receives.
+
+### Step 2: Test
+1. Save workflow
+2. Execute workflow
+3. Look at Node 7 output
+
+**You'll see something like:**
+```json
+{
+  "status": "SUCCESS",
+  "message": "Build completed successfully",
+  "timestamp": "2025-12-01T..."
+}
+```
+
+Notice: **No `repo_full_name` or `commit_sha`** ❌
+
+## 🛠️ REAL FIX: Store Data in workflow.staticData
+
+### In Node 2 "Extract Repo Info", ADD at the top:
+
+```javascript
+// Store data in staticData so all nodes can access it
+$workflow.staticData = $workflow.staticData || {};
+$workflow.staticData.repo_info = {
+  repo_full_name: payload.repository?.full_name || 'unknown',
+  branch: payload.ref?.replace('refs/heads/', '') || 'main',
+  commit_sha: payload.after || '',
+  pusher: payload.pusher?.username || 'unknown'
+};
+```
+
+### Then in Node 7, use:
+
+```javascript
+// Get data from staticData (not from $json)
+const repoInfo = $workflow.staticData.repo_info || {};
+const buildStatus = $json;
+
+const result = {
+  status: buildStatus.status || 'SUCCESS',
+  repo: repoInfo.repo_full_name || 'unknown',
+  branch: repoInfo.branch || 'main',
+  commit: repoInfo.commit_sha ? repoInfo.commit_sha.substring(0, 8) : 'N/A',
+  message: buildStatus.message || 'Build completed',
+  timestamp: new Date().toISOString(),
+  retry_count: ($workflow.staticData.retry_count) || 0
+};
+
+if (result.status === 'SUCCESS') {
+  result.emoji = '✅';
+} else if (result.status === 'FAILED') {
+  result.emoji = '❌';
+}
+
+return result;
+```
+
+## 🎯 Summary:
+
+**The problem:** Node 3 (SSH) doesn't pass Node 2's data through
+
+**The fix:** Store the data in `$workflow.staticData` in Node 2, then read it from staticData in Node 7
+
+**StaticData** is like a shared storage that all nodes can access

+# 🎯 STEP-BY-STEP: Fix Node 7 Data (Follow Exactly)
+
+## The Problem:
+```
+Node 2 has: repo_full_name = "gitadmin/test-repo"
+Node 7 wants: repo_full_name
+BUT: Node 3 loses the data! ❌
+```
+
+## The Solution:
+**Store data in a "shared box" (staticData) that all nodes can access**
+
+---
+
+## STEP 1: Fix Node 2
+
+1. Open **Node 2 "Extract Repo Info"**
+2. Find this line in the code:
+```javascript
+return {
+  repo_name: repoName,
+  repo_full_name: repoFullName,
+  ...
+};
+```
+
+3. **ADD THESE LINES BEFORE the return statement:**
+```javascript
+// NEW: Store data in shared storage
+$workflow.staticData = $workflow.staticData || {};
+$workflow.staticData.repo_info = {
+  repo_name: repoName,
+  repo_full_name: repoFullName,
+  repo_clone_url: repoCloneUrl,
+  branch: branch,
+  commit_sha: commitSha,
+  commit_message: commitMessage,
+  pusher: pusher
+};
+```
+
+4. **Keep the existing return statement too** (don't delete it)
+
+---
+
+## STEP 2: Fix Node 7
+
+1. Open **Node 7 "Format Build Response"**
+2. **REPLACE ALL CODE** with:
+```javascript
+// NEW: Read from shared storage
+const repoInfo = $workflow.staticData.repo_info || {};
+const buildStatus = $json;
+
+const result = {
+  status: buildStatus.status || 'SUCCESS',
+  repo: repoInfo.repo_full_name || 'unknown',
+  branch: repoInfo.branch || 'main',
+  commit: repoInfo.commit_sha ? repoInfo.commit_sha.substring(0, 8) : 'N/A',
+  message: buildStatus.message || 'Build completed',
+  timestamp: new Date().toISOString(),
+  retry_count: ($workflow.staticData && $workflow.staticData.retry_count) || 0
+};
+
+if (result.status === 'SUCCESS') {
+  result.emoji = '✅';
+} else if (result.status === 'FAILED') {
+  result.emoji = '❌';
+} else {
+  result.emoji = '⚠️';
+}
+
+return result;
+```
+
+---
+
+## STEP 3: Save and Test
+
+1. Click **Save** (top-right)
+2. Test with curl:
+```bash
+curl -X POST https://n8n.oky.sh/webhook/openhands-enhanced \
+  -H "Content-Type: application/json" \
+  -d '{"repository": {"full_name": "gitadmin/test-repo"}, "commits": [{"message": "Test"}]}'
+```
+
+3. Check n8n Executions → Node 7 output
+
+---
+
+## Expected Result:
+```json
+{
+  "status": "SUCCESS",
+  "repo": "gitadmin/test-repo",  ← NOW SHOWS ACTUAL NAME!
+  "branch": "main",
+  "commit": "abc12345",          ← NOW SHOWS ACTUAL COMMIT!
+  "message": "Build completed successfully",
+  "emoji": "✅"
+}
+```
+
+---
+
+## Visual Summary:
+```
+Node 2: Creates data → Saves to "shared box" ($workflow.staticData)
+  ↓
+Node 3: SSH runs → (data stays in shared box)
+  ↓
+Node 7: Reads from "shared box" → Has all data! ✅
+```
+
+The "shared box" (staticData) persists across all nodes!
