I have the following project which is working without problem on my local computer. I uploaded it one month ago a post but haven’t found a way to implement it and can’t reply over it.

Current versus Expected behavior

Current Behavior:
- Project deploys successfully locally with `npm run dev`
- API endpoints work locally
- Frontend communicates with backend successfully in development
- Vercel deployment fails with "Debug Failure" error
- Environment variables are properly set in Vercel dashboard

Expected Behavior:
- Successful deployment to Vercel
- API endpoints accessible through Vercel URL
- Frontend able to communicate with deployed API
- Warden Protocol integration working in production

Code, configuration, and steps that reproduce this issue

1. Project Structure:
- React + Vite frontend
- Express.js API
- Warden Protocol integration
- The Graph API integration
- Anthropic Claude API integration

2. Key Configuration Files:
vercel.json:
```json
{
  "version": 2,
  "buildCommand": "npm run build",
  "outputDirectory": "dist",
  "builds": [
    {
      "src": "api/index.ts",
      "use": "@vercel/node",
      "config": {
        "maxDuration": 10,
        "memory": 1024,
        "includeFiles": ["src/tools/**"]
      }
    },
    {
      "src": "package.json",
      "use": "@vercel/static-build",
      "config": {
        "distDir": "dist"
      }
    }
  ],
  "rewrites": [
    { "source": "/api/(.*)", "destination": "/api/index.ts" },
    { "source": "/(.*)", "destination": "/index.html" }
  ]
}

3. Steps to Reproduce:
1. Clone repository
2. Install dependencies: `npm install`
3. Set up environment variables
4. Run locally: `npm run dev` (works)
5. Push to GitHub
6. Deploy to Vercel (fails)
