Creating Dynamic Placeholder accuses error

I saw some issues with dynamically created placeholder and it seems the issue is not resolved. It compiles ok and runs ok as well.

Files:

_config.scss:

$font-families: (
  base: (
    source: google,
    type: sans-serif,
    name: Roboto,
    weights: (400, 700),
  ),
  han: (
    source: google,
    type: sans-serif,
    name: "Black Han Sans",
    weights: (400),
  )
) !default;

$weights: (
  100: light,
  400: normal,
  700: bold,
) !default;

This is the file that is creating font imports and dynamic placholders. _font-config.scss:

@each $family, $font in $font-families {
  @if map-get($font, source) == google {
    $font-name: map-get($font, name);
    $font-type: map-get($font, type);
    $font-weights: map-get($font, weights);

    @each $weight in $font-weights {
      @import url("https://fonts.googleapis.com/css?family=#{$font-name}:#{$weight}");

      %--#{$family}_#{map-get($weights, $weight)} {
        font-family: $font-name, map-get($fallback, $font-type);
        font-weight: $weight;
      }
    }
  }
}
