Sass is having hard time parsing a CSS RGB syntax

Question

Just plugged in gulp-sass into an existing project, and I'm getting an error when I try to write an RGB syntax as follows:

rgb(70 168 255 / 0.05)

The log:

[17:51:58] Starting 'compileCSS'...
Error in plugin "sass"
Message:
    src/xxx.css
Error: Function rgb is missing argument $green.
        on line 77 of src/xxx.css
>>     background-color: rgb(70 168 255 / 0.05);

This is a valid CSS sytnax (which my chrome apparently decided it should be my default syntax). Am I forced to replace all of the occurrences with commas?

Answer 1

Use sass instead of node-sass.

% npm uninstall node-sass
% npm install sass

Answer 2

Update:

dart-sass has been deprecated in favor of sass

According to sass, node-sass doesn't support color level 4. Therefore, I used the dart-sass compiler instead.
