Error while ticking RakSessionCodec

Open Zhongzi8972 opened this issue 1 year ago • 8 comments

Describe the bug

When some Players are changing server with a Velocity server, a error occured in velocity geyser. The player will diconnected from the server. The error in the velocity console is: [21:37:34 ERROR] [org.cloudburstmc.netty.handler.codec.raknet.common.RakSessionCodec]: [/112.12.135.37:9224] Error while ticking RakSessionCodec state=CONNECTED channelActive=true java.lang.NullPointerException: null

  • This bug doesn't happen to every bedrock player. If a bedrock player triggered this bug, he/she could not change the server successfully no matter how many attempts are made, until the velocity server restart.

  • This bug will prevent some bedrock players changing server, but it doesn't prevent these players logining in the first server with velocity----it only occur in the process of changing server.

To Reproduce

  1. Logging in a server with velocity.
  2. use /server xxx to change a server which connected with the velocity
  3. A error occur in geyser-velocity, and the player is disconnected.

It couldn't reproduce 100% successfully, and it seems only occuring in certain server version.

Expected behaviour

No error occur.

Please update Geyser, you're running quite a few commits behind. Further, please send a full server log showing the error

Ok, I will update and try again. And the log is the full server log about the error. It only displayed so much. 1477892c-b17e-4f4b-97e1-49e0f0f91c84

This error should be harmless, as it's occurring after a player disconnects. It doesn't cause the disconnection itself

Thank u, I will try more

I am facing the same with a paper server. It only occurs if i connect with a switch to the server but its causing the player to disconnect.
