Kicked when I join my server

Question

Every time I join my server, I get kicked with the message "internal exception io.netty.handler.codec.encoderexception java.lang.nullpointerexception"

I uninstalled all the plugins that were not there by default and it seems like other people can still join. Just not me.

I posted the log below. Any suggestions are appreciated.
