Code to demonstrate a bug in shelly gen2 firmware 1.0.0-beta6 - 1.0.3 running in Shelly Plug Plus S wherein 2 levels of function calls prevents correct behaviour

call_depth_of_two_breaks_something.js

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

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"
    }
  }
};

function innerFunction() {
  Shelly.call( "PLUGS_UI.SetConfig", { config: bluConfig }, reportConfigError );
}

function outerFunction() {
  innerFunction();
}

//innerFunction(); // Works as intended - leds change color to blue
outerFunction(); // PLUGS_UI.SetConfig Fails with error code -103 

Debug output when calling innerFunction from the top (works as intended)
