Failed: Import Demo Content Install

Hi Team,

We have used updated “Unyson” Plugin & “Backup & Demo Content” Extension. We have maximum php settings. Check this screenshot for phpinfo: https://prnt.sc/rl6pvi

Demo Content import not complete. I am getting a js error. Check the following video for reference: https://prnt.sc/rl6pvi

Error: Ajax error parsererror SyntaxError: Unexpected token O in JSON at position 0. In file: http://localhost/2020/kudil/wp-content/plugins/unyson/framework/extensions/backups/extensions/backups-demo/static/page.js?ver=0.0.0

Kindly assist me, what’s the issue cause.

Thanks
Ram
