Greetings,
I met a problem with my Forge server (47.2.0-1.20.1) that I can't join with the following line. (singleplayer world working fine)
[net.minecraft.server.network.ServerGamePacketListenerImpl/]: Sharyna lost connection: Internal Exception: io.netty.handler.codec.EncoderException: java.lang.NullPointerException: Cannot invoke "net.minecraft.resources.ResourceLocation.toString()" because "p_130086_" is null
At first it was errored with packet size error, but I fixed that with the Connectivity mod, however, after that this popped up and can't find the source of it.
Since the logs are big, I couldn't upload on paste.gg or other site ... so here it is (if the files are deleted, please notice me and I'll upload again.
Debug and Latest log
