I have Error code:

Internal Exception: io.netty.handler.codec.decoderException: java.lang.NullPointerException: Cannot invoke "net.minecraft.network.connectionProtocol$PacketSet.m_178327_(int,net.minecraft.network.FriendlyByteBuf)"

because the return value of "java.util.Map.get(Object)" is null

can someone help please.
