TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received null

Nameless is Here!

So I’m trying to make a gulp task which optimises images (obviously). Here are my files:

gulpfile.esm.js

import gulp	from 'gulp';
import images	from './gulp/tasks/images.js';
import config	from './gulp/config.js';

const build = () => gulp.series(
	gulp.parallel(
		images.build
	)
);

const watch = () => gulp.series(
	build,
	gulp.parallel(
		images.watch
	)
);

let defaultTask;
if (config.env() === 'prod') {
	defaultTask = build;
} else {
	defaultTask = watch;
};

export default defaultTask;

./gulp/tasks/images.js

import gulp		from 'gulp';
import plumber		from 'gulp-plumber';
import changed		from 'gulp-changed';
import gulpIf		from 'gulp-if';
import imagemin		from 'gulp-imagemin';
import pngquant		from 'imagemin-pngquant';
import config		from '../config.js';

const build = () => (
	gulp.src(`${config.source.images}/**/*`)
		.pipe(plumber())
		.pipe(changed(config.build.images))
		.pipe(gulpIf(config.env() === 'prod', imagemin([
			pngquant({ quality: [ 0.8, 0.9 ] }),
			imagemin.mozjpeg({ quality: 80 }),
			imagemin.svgo()
		])))
		.pipe(gulp.dest(config.build.images))
);

const watch = () => gulp.watch(`${config.source.images}/**/*`, build);

export default { watch, build };

The error I get:

Hi there. Sorry for noticing so late. Currently, I don’t have resources to try it out, so I’ll close the issue and reopen it if anything goes wrong. Thanks!
