Package Manager: npm@6.14.15

Describe the bug

If a middleware.ts file is created in the root of the project to use vercel's edge middleware, the config.json file that nitro generates sends to 404 to all /api/* endpoints
For example:

{
  "version": 3,
  "routes": [
    {
      "src": "/_nuxt(.*)",
      "headers": {
        "cache-control": "public,max-age=31536000,immutable"
      },
      "continue": true
    },
    {
      "handle": "error"
    },
    {
      "status": 404,
      "src": "^(?!/api).*$",
      "dest": "/404.html"
    },
    {
      "handle": "filesystem"
    },
    {
      "src": "/(.*)",
      "dest": "/"
    }
  ]
}

But if not have that middleware.ts file, the build not generates this exeception to api endpoints
