Cannot invoke "net.minecraft.core.Holder.a()" because "holder" is null
Lucien2714 opened this issue ยท 9 comments
normal players can't trigger the commands they will get a message, "I'm sorry, but you do not have the permission to perform this command. Please contact the server administrators if you believe that this is in error."
Config: default
Server: papermc1.18.2 with geyser
I checked the config and I am a little bit confused about it, is there something I didn't config correctly?
Which server platform do you use? In case of proxies like BungeeCord, you have to give the users the permission on the proxy not like usually on the Spigot server.
I am using Papermc with the Geyser plugin for bedrock players to join my server. And I tried the /setskin command as op, every time I will just be kicked out of the server, after rejoining I was able to see my skins changed.

test2 is a OP in the server

For players who isn't a OP the log only prints
[xx:xx:xx] [Server thread/INFO]: xxx issued server command: /setskin xxxxx
Please post the server log for that time.
v4.8.0, I think it is the latest version
Which version of ProtocolLib do you have?
sry I didn't check github yesterday. I tried without Geyser and the problems still exist. Here is my test server(Idk why I couldn't put it on github so I am putting it on google drive). download link. btw the server is set to run it 25564 port since my main server was running on 25565.
