    I have an issue, my server version: Arclight 1.19.2.

    I don't know whether I need to install anything before I've tried to join the server. I already have Forge 1.19.2 and all the right versions of mods in my folder.

    The server turns on but, when I try to join

    the following message pops up: Internal Exception: io.netty.handler.codec.EncoderException:java.lang.NullPointerException: Cannot invoke"net.minecraft.resources.ResourceKey.m_135782_()" because "dimension" is null


    What should I do about it?

    Share your client log

    1. open your minecraft installation path

    (enter %appdata%/.minecraft in the file explorer )

    2. open the logs folder

    3. open the "latest" or "latest.log" file with a text editor

    4. copy and paste the content of the file to https://mclo.gs/

    5. send the link here
