[LukaszGrela]

Types of property 'importers' are incompatible.
                    Type 'NodePackageImporter[]' is not assignable to type '(Importer<"async"> | FileImporter<"async"> | NodePackageImporter)[]'.
                      Type 'NodePackageImporter' is not assignable to type 'Importer<"async"> | FileImporter<"async"> | NodePackageImporter'.

export default defineConfig(()=({
    css: {
        preprocessorOptions: {
            scss: {
                api: 'modern-compiler',
                importers: [new NodePackageImporter()]
            }
        }
    },
});

vite 6.2.2, sass-embedded 1.86.3

Little bit different is when UserConfig is used directly

No overload matches this call.
  The last overload gave the following error.
    Type 'NodePackageImporter' is not assignable to type 'Importer<"async"> | FileImporter<"async"> | NodePackageImporter'.ts(2769)
index.d.ts(3625, 18): The last overload is declared here.

export default defineConfig({
    css: {
        preprocessorOptions: {
            scss: {
                api: 'modern-compiler',
                importers: [new NodePackageImporter()]
            }
        }
    },
