• You didn't use /reload

Describe the question
I am trying to change the user's display name but I am getting an error: FieldAccessException: Field index 0 is out of bounds for length 0

Expected behavior
Not getting errors

Code

PacketContainer packet = new PacketContainer(PacketType.Play.Server.PLAYER_INFO);
packet.getPlayerInfoActions().write(0, EnumSet.of(EnumWrappers.PlayerInfoAction.UPDATE_DISPLAY_NAME));

WrappedGameProfile wgp = new WrappedGameProfile(uuid, orgName);
packet.getPlayerInfoDataLists().write(1,
    Collections.singletonList(
        new PlayerInfoData(wgp, 50, NativeGameMode.ADVENTURE, WrappedChatComponent.fromLegacyText(newName))
    )
);

ProtocolLibrary.getProtocolManager().sendServerPacket(player, packet);

Additional context
Using server version 1.19 and plugin version 5.1.0

Hi,

the code you sent is compatible with 1.19.3 or later. If you are using 1.19, you need to change your code:

PacketContainer packet = new PacketContainer(PacketType.Play.Server.PLAYER_INFO);
packet.getPlayerInfoAction().write(0, EnumWrappers.PlayerInfoAction.UPDATE_DISPLAY_NAME);

WrappedGameProfile wgp = new WrappedGameProfile(uuid, orgName);
packet.getPlayerInfoDataLists().write(0,
    Collections.singletonList(
        new PlayerInfoData(wgp, 50, NativeGameMode.ADVENTURE, WrappedChatComponent.fromLegacyText(newName))
    )
);

ProtocolLibrary.getProtocolManager().sendServerPacket(player, packet);
