[1.16.1] Disconnected from server on join due to Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException #37

When attempting to join a 1.16.1 Forge server with VoxelMap, I am able to join for a second and then I immediately get disconnected for the following error:

Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(23) + length(8) exceeds writerIndex(23): PooledUnsafeDirectByteBuf(ridx:23, widx: 23, cap:23)

The issue persisted on every server connection attempt until I removed VoxelMap. The server console log indicates VoxelMap is having issues with packets:

I am also including a link to my forge support thread on the same issue which is where I was able to pinpoint that it was voxelmap. You can find latest and debug logs there although I don't know if this will be helpful. https://forums.minecraftforge.net/topic/89510-1161-internal-exception-ionettyhandlercodecdecoderexception-javalangindexoutofboundsexception-readerindex23-length8-exceeds-writerindex23-pooledunsafedirectbytebufridx23-widx-23-cap23/
