css variables doesn't get interpolated

[PlopTheReal]

For the given json:

{
    "backgroundColor": "#3215B3",
}

the following doesn't work ($backgroundColor doesn't get replaced):

:root {
  --backgroundColor: $backgroundColor;  
}

but this one works:

html {
  color: #3215B3; 
}

I'm using the CLI.

This is a Sass language feature, not an issue with this module. You need to manually interpolate when setting CSS custom property values like this:

:root {
  --backgroundColor: #{$backgroundColor};
}
