Why doesn't sass compile to css vs code?

Question

Sass

sass not compiling to css.
In style.css it gives /* No CSS *//*# sourceMappingURL=style.css.map */
In style.map

{
    "version": 3,
    "mappings": "",
    "sources": [
        "style.scss"
    ],
    "names": [],
    "file": "style.css"
}

in setting.jons

{
    "liveSassCompile.settings.formats": [
        {
            "format": "expanded",
            "extensionName": ".css",
            "savePath": "/css/",
        }
    ],
    "explorer.confirmDelete": false
}

What is the problem?
