Hey guys, Deployments are not showing after adding vercel.json file to project. here's how it looks like

 {
  "crons": [
    {
      "path": "/api/cron/challenge",
      "schedule": "*/100 * * * *"
    }
  ],
  "functions": {
    "api/*.ts": {
      "memory": 3008,
      "maxDuration": 30
    }
  }
}

Why is this happening?
