Error passing a list to a SASS mixin: "] expected"

Question

I'm passing a list to a SASS mixin and it works (no error in the browser or console) but my editor (VS Code) says there are errors. The code is:

  @include gridAuto(
    320px, 
    [
      ['sm', 2],
      ['', 1],
      ['lg', 3],
    ],
    var(--space-xl), 
    var(--space-xxl)
  );

I get errors on this line ['sm', 2],. The errors:

] expected
] expected
) expected
at-rule or selector expected

These are the styles dependencies the starter theme is using:

"autoprefixer": "^9.4",
"css-loader": "^0.28.9",
"cssnano": "~4.0.5",
"node-sass": "~4.9.4",
"postcss-custom-properties": "^9.1.1",
"postcss-loader": "~2.1.0",
"postcss-safe-parser": "~3.0",
"sass-loader": "~6.0",
"style-loader": "^0.22.1",
"stylelint": "^8.4.0",
"stylelint-config-standard": "~18.2.0",
"stylelint-webpack-plugin": "^0.10.5",

I attach a screenshot

It seems the SCSS validator built into VS Code is struggling to understand this construct. As you are using the stylelint extension for VS Code, you can turn off the built-in validator by adding the following to your user settings:

"scss.validate": false

(The stylelint extension itself doesn't have a problem with this construct.)
