RuntimeError: abort(RuntimeError: abort(both async and sync fetching of the wasm failed)

I'm trying to load PhpWeb in NextJS app, but it's failing as below:

Unhandled Runtime Error
RuntimeError: abort(RuntimeError: abort(both async and sync fetching of the wasm failed). Build with -s ASSERTIONS=1 for more info.). Build with -s ASSERTIONS=1 for more info.

Call Stack

node_modules/php-wasm/php-web.js (9:11689)

Version: php-wasm@0.0.4-b

I'm loading <Drupal/> component by:

const Drupal = dynamic(() => import("../components/Drupal"), {ssr: false});

where Drupal class is defined as:

export default class Drupal extends React.Component {
	constructor(props) {
		super(props);
	}

	componentDidUpdate(prevProps, prevState) {
	}

	async componentDidMount() {
		const PhpWeb = (await import('php-wasm/PhpWeb')).PhpWeb;
		const php = new PhpWeb;
	}

	render() {
		return (
			<div className={styles.drupal}>
				Drupal
			</div>
		)
	}
}

Any ideas why this error happens? In php-web.js file?
