🔧 MANUAL FIX - Follow These EXACT Steps

The Problem:

Cannot set properties of undefined (setting 'repo_info')

Root Cause: $workflow.staticData doesn't work in n8n code nodes the way we're using it.

---

SOLUTION: Remove staticData Completely

Step 1: Open n8n Workflow

1. Go to: https://n8n.oky.sh
2. Open: "Gitea → OpenHands Enhanced CI/CD" workflow
3. You should see all the nodes in a flow

Step 2: Fix Node 2 - "Extract Repo Info"

1. Click on Node 2 (the blue code node)
2. Find the JavaScript code (should be in a text area)
3. REPLACE THE ENTIRE CODE with this:

// Extract repository and commit information from Gitea webhook
const payload = $input.item.json;

// Extract key information
const repoName = payload.repository?.name || 'unknown';
const repoFullName = payload.repository?.full_name || 'unknown';
const repoCloneUrl = payload.repository?.clone_url || '';
const branch = payload.ref?.replace('refs/heads/', '') || 'main';
const commitSha = payload.after || '';
const commitMessage = payload.commits?.[0]?.message || 'No message';
const pusher = payload.pusher?.username || 'unknown';

// Create task message for OpenHands SDK
const task = 'Build and test project ' + repoFullName + ' on branch ' + branch + '. ' +
             'Latest commit: "' + commitMessage + '". ' +
             'Clone the repository from ' + repoCloneUrl + ' and run: npm install && npm test && npm build. ' +
             'Report any errors found.';

// IMPORTANT: Just return the data - it will flow to the next node
return {
  repo_name: repoName,
  repo_full_name: repoFullName,
  repo_clone_url: repoCloneUrl,
  branch: branch,
  commit_sha: commitSha,
  commit_message: commitMessage,
  pusher: pusher,
  task: task,
  timestamp: new Date().toISOString(),
  status: 'PENDING',
  retry_count: 0
};

4. Click "Update" or Save

Step 3: Fix Node 7 - "Format Build Response"

1. Click on Node 7 (later in the flow)
2. Find the JavaScript code
3. REPLACE THE ENTIRE CODE with this:

// Use the data from $json (which has everything from previous nodes)
const item = $json;

const result = {
  status: item.status || 'SUCCESS',
  repo: item.repo_full_name || 'unknown',
  branch: item.branch || 'main',
  commit: item.commit_sha ? item.commit_sha.substring(0, 8) : 'N/A',
  message: item.message || 'Build completed',
  timestamp: new Date().toISOString(),
  retry_count: 0
};

// Add emoji based on status
if (result.status === 'SUCCESS') {
  result.emoji = '✅';
} else if (result.status === 'FAILED') {
  result.emoji = '❌';
} else {
  result.emoji = '⚠️';
}

return result;

4. Click "Update" or Save

Step 4: Save the Entire Workflow

1. Click "Save" (top-right of the workflow editor)
2. Make sure the workflow is ACTIVE (toggle switch should be green/blue)

Step 5: Test It

1. Click "Execute Workflow" button (top-right)
2. Use this test data:

{
  "repository": {
    "name": "test-repo",
    "full_name": "gitadmin/test-repo",
    "clone_url": "https://git.oky.sh/gitadmin/test-repo.git"
  },
  "ref": "refs/heads/main",
  "after": "abc123def456",
  "commits": [{"message": "Test webhook with real data"}],
  "pusher": {"username": "gitadmin"}
}

3. Click "Execute Workflow"

Step 6: Check the Result

Look at Node 7 "Format Build Response" output. You should see:

{
  "status": "SUCCESS",
  "repo": "gitadmin/test-repo",  ← REAL REPO NAME! ✅
  "branch": "main",
  "commit": "abc12345",          ← REAL COMMIT! ✅
  "message": "Build completed successfully",
  "timestamp": "2025-12-01T19:xx:xx.xxxZ",
  "retry_count": 0,
  "emoji": "✅"
}

Step 7: Export the Working Workflow

1. In n8n, go to the workflow editor
2. Click "..." menu (three dots, top-right)
3. Select "Export"
4. Download the JSON file
5. Upload it to the repository as openhands-enhanced-WORKING.json

What Changed:

BEFORE (Broken):

• Node 2: Tried to use $workflow.staticData.repo_info = {...} ❌
• Node 7: Tried to read $workflow.staticData.repo_info ❌

AFTER (Working):

• Node 2: Just returns data (flows to next node) ✅
• Node 7: Reads data from $json ✅

The Fix: Data flows through nodes normally using $json, no staticData needed!
