Describe the bug
If you somehow managed to create a custom entity attribute, and try to log in on a server with packetevents installed, you will get an exception and will not be able to log in.
Software brand
Spigot 1.20.1
Plugins
PacketEvents, LibsDisguises
How To Reproduce
- Using cursed reflection code, add a custom entity attribute to all entities
- Launch the server
- Attempt to join
Expected behavior
The player should be able to join, the custom attribute should be ignored.
Screenshots
Additional context
After some digging, I figured out that this code literally allows null attribute values, causing the write method to throw an NPE, causing the whole disconnect. Adding a simple null check to the first link fixed the entire issue.
