Hi, I created a custom plugin for tab for 1.16 and 1.18, today I wanted to update it to 1.19 but I encountered this problem

I tried with the latest build on spigot and also the latest dev build. The server is on latest paper 1.19.4 build.

Error also on pastebin

Ok thanks, I tried and it seems to work.

The internal structure of the PlayerInfo Packe changed with 1.19. Instead of one single action, it now stores a set of actions (e.g. update latency or update display name) and only the fields required by the actions will be sent to the client. You can find an example on how to do this in 1.19.4 here: https://github.com/lukalt/PacketWrapper/blob/master/src/main/java/com/comphenix/packetwrapper/wrappers/play/clientbound/WrapperPlayServerPlayerInfo.java
