Code to demonstrate behaviour of Object.create (not working) vs cloning through json (working) in shelly gen2 firmware 1.0.0-beta6 - 1.0.3 running in Shelly Plug Plus S

clone_vs_object_create.js

function reportConfigError(res, ec, em) {
    console.log("Config update error", ec, em);
}

function cloneObject(something) {
  let str = JSON.stringify(something);
  return JSON.parse(str);
}

let bluConfig = {
  leds: {
    mode: "switch",
    colors: {
      "switch:0": {
        on: {
          rgb: [ 0, 0, 100],
          brightness: 80 },
        off: {
          rgb: [ 0, 50, 0 ],
          brightness: 10 }
      },
      power: { brightness: 100 }
    },
    night_mode: {
      enable: false,
      brightness: 100,
      active_between: [
        "00:00",
        "00:00"
      ]
    }
  },
  controls: {
    "switch:0": {
      in_mode: "momentary"
    }
  }
};

// let clone = Object.create(bluConfig); // Results in error -103 Missing or bad argument 'leds or controls'! from PLUGS_UI.SetConfig
let clone = cloneObject(bluConfig); // Works as expected.

Shelly.call( "PLUGS_UI.SetConfig", { config: clone }, reportConfigError );

See https://gist.github.com/anttikuuskoski/08c246aba218d74f65c752d55f836dae which demonstrates that Object.create or something in the running environment is not entirely sane.
