I have a React app that needs to parse some XML data. I plan to use a package to do this job. The packages xml2js and @types/xml2js are installed. During testing the following error appeared:

sax.js:222 Uncaught TypeError: Cannot read properties of undefined (reading 'prototype')
    at sax.js:222:46
   ...

Here's the file containing the code. The syntax should be correct according to the docs. The other components shouldn't be causing this particular error since they are not wired to it yet.

import {useState, useEffect} from 'react'
import x2j from 'xml2js';

export default function EventWindow(props: { xml: string; }) {
  const {xml} = props;
  const [eventText, setEventText] = useState('');
  const [eventChoices, setEventChoices] = useState('');

  useEffect(() => {
    const ps = new x2j.Parser();
    ps.parseString(xml, (err, res) => {
      console.log(res)
    })
  }, [xml])

  return (
    <div>
      <EventSimText text={eventText || "Error Detected."} />
      <EventSimChoices choicesArr={eventChoices} />
    </div>
  )
}

Thanks
