Issue with onPacketReceiving

[Nuutrai]

Describe the bug onPacketReceiving is producing an IndexOutOfBounds exception.

To reproduce

1. Install ZulfBungee version v0.9.8 on all servers
2. Install ProtocolLib v5.3.0-SNAPSHOT-732 on Paper servers
3. Join the proxy server
4. Check console

Expected behavior I was expecting ZulfBungee to register the connection of the player

Screenshots Stack trace is at the end
