How to resolve the deprecation warning ‘The legacy JS API is deprecated’ when using Dart Sass?

I’m getting the following message when building my project in js, but Dart Sass is already up-to-date. What should I do in this situation?

[@localhost frontend]$ npm run lumis:build

…/frontend/gulpfile.mjs

[22:21:55] Starting ‘lumis:build’…

[22:21:55] Starting ‘lumisClean’…

[22:21:55] Finished ‘lumisClean’ after 61 ms

[22:21:55] Starting ”…

[22:21:55] Starting ‘lumisLayout’…

[22:21:55] Starting ”…

[22:21:55] Finished ” after 17 ms

[22:21:55] Finished ” after 54 ms

[22:21:55] Finished ‘lumisLayout’ after 58 ms

[22:21:55] Finished ‘lumis:build’ after 123 ms

Deprecation Warning: The legacy JS API is deprecated and will be removed in Dart Sass 2.0.0.

My gulpfile.mjs:

import { deleteAsync } from “del”;

import gulp from “gulp”;

import dartSass from “sass”;

import gulpSass from “gulp-sass”;

import autoPrefixer from “gulp-autoprefixer”;

import fileInclude from “gulp-file-include”;

import replace from ‘gulp-replace’;

import dotenv from ‘dotenv’;

import concat from ‘gulp-concat’;

import uglify from ‘gulp-uglify’;

import gulpIf from ‘gulp-if’;

import fs from ‘fs’;

dotenv.config()

const { dest, parallel, series, task, watch } = gulp;

const sass = gulpSass(dartSass);
