If the current behaviour is a bug, please provide the steps to reproduce.

$ npm i -g preact-cli
$ preact create default my-project
$ cd my-project
$ preact serve --server config                                                                                                                                 
TypeError: Path must be a string. Received undefined

What is the expected behaviour?
That's the output I get with preact-cli v2.1.1

$ preact serve --server config
{
  "rewrites": [
    {
      "source": "**",
      "destination": "/index.html"
    }
  ],
  "headers": [
    {
      "source": "**",
      "headers": [
        {
          "key": "Cache-Control",
          "value": "public, max-age=3600, no-cache"
        },
        {
          "key": "Access-Control-Max-Age",
          "value": "600"
        }
      ]
    },
    {
      "source": "/sw.js",
      "headers": [
        {
          "key": "Cache-Control",
          "value": "private, no-cache"
        }
      ]
    },
    {
      "source": "**/*.chunk.*.js",
      "headers": [
        {
          "key": "Cache-Control",
          "value": "public, max-age=31536000"
        }
      ]
    }
  ],
  "public": "build"
}

Not enough non-option arguments: got 0, need at least 1

C:\ws\preact-book-example>preact serve --server config
TypeError: Path must be a string. Received undefined

adding a --dest option allows it to succeed. Somehow the default has been dropped, maybe?

$ preact serve --server config --dest firebase.json

@lecstor Thx, that really helps! But I'll keep this issue open until the README is fixed accordingly: https://github.com/developit/preact-cli#deploying

I.s.o. 'fixing' the README, better fix the code 👍
