As of recently, users no longer lose their inventory when they fall into the end. I found out that it is the Red Protect.
I found the lines:

command-on-damage {
            VOID="spawn {player}"
        }

That means as soon as they get damage in the void they are automatically teleported out. You don't lose your items. but what they should. How can I paraphrase that the players die again as usual in the Void and lose their items?

If I change it to

command-on-damage {
             VOID = "kill {player}"
         }

I get a permanent message in the chat until the user is dead. but then his inventory is also empty
