A message keeps randomly popping up on my chat:
Error Unable to intercept a read client packet. (java.lang.IllegalArgumentException: Unable to find a field null with the type com.mojang.authlib.GameProfile in net.minecraft.network.protocol.login.PacketLoginInStart) occured in com.comphenix.protocol.injector.netty.ChannelInjector"1e0313
And i don't know what it means.
I am using Aternos host.

I use SuperVanish 6.2.7 (1.18) So it can be the reason why i get the error. And also there is an error in the logs that
SuperVanish does not work propely. I think it might be that. The problem might be solved jus't by waiting for SuperVanish 1.19 and replacing 1.18 version with that.

Plz help. Or at least tell how to fix this.
░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░

This is fixed in the latest dev builds, download them from here: https://ci.dmulloy2.net/job/ProtocolLib/lastSuccessfulBuild/

Unfortunately i cant download that file to my aternos server, because all plugins needs to be downloaded directly from Spigot. So i'll just wait for new Supervanish version or new ProtocolLib version.
