Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(30) + length(1) exceeds uriter Index(30): PooledUnsafeDirectByteBufcridx: 30, uidx: 30, cap: 30)

Hi, when I try to enter a server with mods I get this error. I have already restarted several times the launcher and others, but I still get it. I would like help to know what the error is and how to fix it please.

Please add -Dforge.logging.mojang.level=debug to the JVM Arguments of your Launcher then (after producing the error) post debug.log from the logs folder.
