I used reqn addon and tried to do a new project with the involvement of discord webhooks.​

Code (Skript):

1. command /post:test:
2.     trigger:
3.         set {_custom} to "something"
4.         wait a second
5.         send a "post" request to "https://discord.com/api/webhooks/token" with the body "content=Test this var: %{_custom}%&" and the headers "content-type: application/x-www-form-urlencoded"
6.         set {_r} to the last http response
7.         set {_c} to {_r}'s status code
8.         set {_b} to {_r}'s body
9.         broadcast {_b}, {_c}

(The webhook URL is just a dummy for this post)

The code seems fine. But when the post request is sent, the webhook's content/message is Test this var: <none>
Why does the {_custom} variable is <none>. Though it is set to "something"?
