Register csscomb as default formatter that not work

[magicds]

Environment

• VSCode Version: 1.37.0
• OS Version: windows
• CSScomb Version: 5.2.3

I used this config to set CSScomb as default formatter

{
  "[scss]": {
    "editor.defaultFormatter": "mrmlnc.vscode-csscomb"
  },
  "[css]": {
    "editor.defaultFormatter": "mrmlnc.vscode-csscomb"
  }
}

Actual behavior

When I use Alt + Shift + F or Format Document to format some file I will get an error extension 'csscomb' cannot format 'somefile'
