Config copy not working without dest

[tiloio]

The documentation says:

The config can also provide an optional dest https://stenciljs.com/docs/config/

But when I do for example this on the app start seed:

import { Config } from "@stencil/core";
// https://stenciljs.com/docs/config

export const config: Config = {
  globalStyle: "src/global/app.css",
  globalScript: "src/global/app.ts",
  copy: [
    {src: "./../readme.md"}
  ],
  outputTargets: [
    {
      type: "www"
      // uncomment the following line to disable service workers in production
      // serviceWorker: null
    }
  ]
};

I am getting this error on npm start:

[19:33.4]  dev server: http://localhost:3333/

And this as the npm run build result:

When I change the config copy part to the following, then everything works as expected:

  copy: [
    {src: "./../readme.md", dest: "./readme.md"}
  ],
