+# 🎯 Workflow Complete! But Data Shows "unknown"
+
+## ✅ Current Status
+
+The workflow is **working perfectly**:
+- All nodes execute
+- No errors
+- Completes successfully
+- Returns proper structure
+
+## ❌ Issue: Data Shows "unknown"
+
+**Current output:**
+```json
+{
+  "status": "SUCCESS",
+  "repo": "unknown",        ← Should be: "gitadmin/test-repo"
+  "branch": "main",
+  "commit": "N/A",          ← Should be: "abc123"
+  "message": "Build completed successfully",
+  "timestamp": "2025-12-01T19:02:06.631Z",
+  "retry_count": 0,
+  "emoji": "✅"
+}
+```
+
+## 🔍 Root Cause
+
+Node 7 tries to reference Node 2 data using:
+```javascript
+const repoInfo = $('Extract Repo Info').item.json;
+```
+
+**The issue:**
+- `$('Node Name')` syntax doesn't work in n8n v2
+- Should use: `$node["Extract Repo Info"].json` or `$json`
+
+## 🛠️ Fix: Update Node 7 to Use Current Item Data
+
+In Node 7 **"Format Build Response"**, replace the code with:
+
+```javascript
+// Use $json to get data from previous node (Node 6)
+const buildStatus = $json;
+
+// The repo/branch/commit data comes from Node 2 "Extract Repo Info"
+// We need to get it from the workflow data flow
+const repoInfo = $node["Extract Repo Info"].json;
+
+const result = {
+  status: buildStatus.status,
+  repo: repoInfo.repo_full_name,
+  branch: repoInfo.branch,
+  commit: repoInfo.commit_sha ? repoInfo.commit_sha.substring(0, 8) : 'N/A',
+  message: buildStatus.message,
+  timestamp: new Date().toISOString(),
+  retry_count: ($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;
+```
+
+### Alternative (Simpler): Use Test Webhook
+
+The easiest way to see the full data flow is to use the **Test Webhook** from n8n editor:
+1. Open workflow in n8n
+2. Click **"Execute Workflow"** button
+3. Send test payload
+4. Check each node's output - you'll see the actual data flowing through
+
+### Alternative: Check Node Outputs
+
+In n8n execution view:
+1. Click on **Node 2 "Extract Repo Info"**
+2. See output: Should show actual repo_full_name, commit_sha, etc.
+3. Click on **Node 6 "Check Build Status"**
+4. See output: Shows status and message
+5. Node 7 should read from both of these
+
+## ✅ Expected After Fix
+
+```json
+{
+  "status": "SUCCESS",
+  "repo": "gitadmin/test-repo",  ← Actual repo name
+  "branch": "main",
+  "commit": "abc12345",          ← First 8 chars of commit
+  "message": "Build completed successfully",
+  "timestamp": "2025-12-01T19:02:06.631Z",
+  "retry_count": 0,
+  "emoji": "✅"
+}
+```
+
+## 🎯 Bottom Line
+
+**Your workflow IS WORKING!** ✅
+The "unknown" values are just a data reference issue, not a functional problem.
