  • Can't connect to server

    I created an assembly on fabric, added mods to the Aternos server, but when I try to access the server, an error appears:


    Internal Exception: io.netty.handler.codec.DecoderException:

    java lang.Nullpointerexception: Cannot invoke "java.util.function.Supplier.geto"

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



    what to do?
