Not working on XSShunter redirect

[mikkz]

Hello,

The javascript returns:

(index):103 Uncaught TypeError: Cannot read properties of null (reading 'outerText')
at get_dom_text ((index):103:17)
at (index):243:29

When triggering the payload thru the xss redirect of xsshunter.

Any help on this?

It is working when directly using the payload on the self hosted.
