internal exception io.netty.handler.codec.decoderexception

[Katarinaa]

I made a forge server with the launcher and upon joining i get a error message.

(Medieval mod 1.19.2 client and server)

internal exception io.netty.handler.codec.decoderexception java.lang.indexoutofboundsexception:readerIndex(26955) +lenght(4) exceeds writerIndex(736955:PooledUnsafeDirectByteBuf(ridx: 26955, widx: 26955, cap: 26955)

Does anyone know how to fix this problem?

Thank you in advance

Do you get this error on server or on client?

im getting erros just like this (the numbers are different) Im playing a slightly altered better minecraft modpack, i can play SP just fine with no issues. i copied the modpack to my laptop for my son. if either of us opens a world to lan the other cannot join, with this error popping up. doesnt matter who 'hosts', neither of us can join the other. i can find NO solutions at all. we are both frustrated. how can i get a log to post?
