Compiling error: $color

[yitong-zhang]

When I test the compiler with bootstrap's original scss, I got the below error:

Error!: $color:"var(--bs-primary-rgb)"is not a color for 'rgba'
on line 47 of ..../_functions.scss
from line 11 of .../bootstrap.scss

line 40-47 of ..../_functions.scss:

// stylelint-disable scss/dollar-variable-pattern
@function rgba-css-var($identifier, $target) {
  @if $identifier == "body" and $target == "bg" {
    @return rgba(var(--#{$variable-prefix}#{$identifier}-bg-rgb), var(--#{$variable-prefix}#{$target}-opacity));
  } @if $identifier == "body" and $target == "text" {
    @return rgba(var(--#{$variable-prefix}#{$identifier}-color-rgb), var(--#{$variable-prefix}#{$target}-opacity));
  } @else {
    @return rgba(var(--#{$variable-prefix}#{$identifier}-rgb), var(--#{$variable-prefix}#{$target}-opacity));
  }

line 11 of .../bootstrap.scss:

@import "variables";
