SyntaxError: missing ) after argument list error when run gulp task with frontend-maven-plugin

Question

I have this task in gulpfile.js:

gulp.task('sass', async function () {
    log('Compiling Sass --> CSS');

    var sassOptions = {
        outputStyle: 'nested' // nested, expanded, compact, compressed
    };

    return gulp
        .src(config.sass)
        .pipe($.plumber({errorHandler: swallowError}))
        .pipe($.sourcemaps.init())
        .pipe($.sass(sassOptions))
        .pipe($.autoprefixer())
        .pipe($.sourcemaps.write())
        .pipe(gulp.dest(config.tmp + '/css'));
});

when I run this task with gulp sass command, everything is ok, but with frontend-maven-plugin i get this errors:
