WordPress to Contentack Blog Migration

I’m trying to figure out how to migrate the blog posts from WordPress website to Contentstack.

I was trying to follow this guide:
https://www.contentstack.com/docs/developers/content-migration/wordpress-to-contentstack

I installed node.js on a vps machine and instaled WordPress-xml-to-contentstack-converter.

In WordPress I exported the blog to a xml file and copied that to the vps.

As described in the guide I added the xml file path to the configuration file index.json.

When I run “npm run export” it shows this error: “error: failed to parse xml:”

Please do you know what I’m doing wrong?
