- error
Environment:

In case it is relevant: I use PacketEvents, but I don't listen to or write to the brand channel with it.

The error only appears on 1.20.6, on 1.20.5 it works fine.

Version:
This server is running CraftBukkit version 4184-Spigot-fcd94e2-16c9767 (MC: 1.20.6) (Implementing API version 1.20.6-R0.1-SNAPSHOT)
Guidelines Read:
Yes

When I use player.sendPluginMessage() on the minecraft:brand channel, I get the following error. This also prevents joining when used in an onJoin event:

My actual code, in case that my way of doing it is unsupported. If there is a better or new way/API of doing it, please tell me as well:

public void setBrand(String brand)
{
    this.brand = ChatColor.translateAlternateColorCodes('&', brand) + ChatColor.RESET;
    this.updateAllBrands();
}

private void updateAllBrands()
{
    for (Player onlinePlayer : Bukkit.getOnlinePlayers()) updateBrand(onlinePlayer);
}

private void updateBrand(final Player player)
{
    final ByteBuf buf = Unpooled.buffer();

    ByteBufUtil.writeString(buf, Placeholders.replacePlaceholders(this.brand, player));

    player.sendPluginMessage(AntiCheatAddition.getInstance(), MessageChannel.MC_BRAND_CHANNEL.getChannel().orElseThrow(), ByteBufUtil.toArray(buf));
    buf.release();
}

@Override
public void enable()
{
    Bukkit.getMessenger().registerOutgoingPluginChannel(AntiCheatAddition.getInstance(), MessageChannel.MC_BRAND_CHANNEL.getChannel().orElseThrow());
    this.setBrand(loadString(".brand", "Some Spigot"));

    final long refreshRate = loadLong(".refresh_rate", 0);
    if (refreshRate > 0) Bukkit.getScheduler().runTaskTimer(AntiCheatAddition.getInstance(), this::updateAllBrands, 20, refreshRate);
}

@EventHandler
public void onJoin(PlayerJoinEvent event)
{
    // Add the mc brand channel to the player's channels.
    PLAYER_CHANNELS_FIELD.from(event.getPlayer()).asSet(String.class).add(MessageChannel.MC_BRAND_CHANNEL.getChannel().orElseThrow());
    updateBrand(event.getPlayer());
}
