NPC Cannot transfer Player to a server

[lionel760x]

So im trying to make when a player punches a NPC,
The player will be teleported to different server.

But the problem is, It doesnt teleport at all,
It always says unknown command: server test.

Btw i use WaterdogPE and NukkitX.

I think I know how to solve this problem by using a transfer plugin for the
Nukkit server, but I don't know how to write plugins, Is there any fast transfer plugin
for NukkitX? Please?

The command isn't registered on the server (NukkitX), it's registered on the proxy, making it only accessible to the client.
