Expected behavior: Skin working

Actual behavior Sking not working

Resources (screenshots, code snippets etc.)

I am using this from the example and then the class="test-skin" in my index.html body element and not getting any results. Additionally the import for

@import "../node_modules/ng-uikit-pro-standard/assets/scss/pro/variables";
@import "../node_modules/ng-uikit-pro-standard/assets/scss/pro/skins";

Are not working for me

$skins: () !default;
$skins: map-merge(
  (
    "test": (
      "skin-primary-color": black,
      "skin-navbar": #fff,
      "skin-footer-color": #fff,
      "skin-accent": #fff,
      "skin-flat": #fff,
      "skin-sidenav-item": #fff,
