Can we have a portal in Next.js

I'm using Next.js with my React app, and I'm having a trouble with creating modal in portal, it throws an error 'Target container is not a DOM element.', here is my code.

import React, { useEffect } from 'react';
import ReactDOM from 'react-dom';
import PropTypes from 'prop-types';
import classes from './listModal.scss';

const EditorListModal = (props) => {
  let container;
  if (typeof window !== 'undefined') {
    const rootContainer = document.createElement('div');
    const parentElem = document.querySelector('#__next');
    parentElem.appendChild(rootContainer);
    container = rootContainer;
  }
  const isShown = props.show ? classes['editor-listModal--open'] : '';
  const element = (
    <div className={`${classes['editor-listModal']} ${isShown}`}>
      // Modal Content
    </div>
  );

  return ReactDOM.createPortal(element, container);
};

EditorListModal.propTypes = {
  show: PropTypes.bool
};

export default React.memo(EditorListModal);

It's going to break during the ssr because the container is not initialized. You could try to skip rendering when there is no portal:

return container ? ReactDOM.createPortal(element, container) : null;
