esm using gulp 4 webpack-stream setup not working

I implemented this per example using index.js pointing to main.js, also using gulp with webpack-stream and when it gets to gulp task scripts below

function scripts() {
    return gulp.src('./index.js')
        .pipe(gulpWebpack({
            entry: {
                'main-new': './index.js'
            },

I get this error

I figure out why just corrected my gulp pipe entry src I was pointing both gulp src and entry src to index.js that contains the esm module.

function scripts() {
    return gulp.src('./index.js')
        .pipe(gulpWebpack({
            entry: {
                'main-new': './src/js/main.js'
            },
