My plugin has ERROR occured since commit "update 1.21.6" of ProtocolLib at PaperMC 1.20.4-1.21.5 servers.

There is no problem with 1.21.6.

My code:

            public void onPacketSending(PacketEvent event) {
                PacketContainer packet = event.getPacket();
                int idx = 1;
                if (MinecraftVersion.FEATURE_PREVIEW_UPDATE.atOrAbove()) {
                    Set<PlayerInfoAction> actions = packet.getPlayerInfoActions().read(0);
                    if (!actions.contains(PlayerInfoAction.UPDATE_DISPLAY_NAME)) return;
                } else {
                    if (packet.getPlayerInfoAction().read(0) != PlayerInfoAction.ADD_PLAYER) return;
                    idx = 0;
                }
                List<PlayerInfoData> playerInfoDataList = packet.getPlayerInfoDataLists().read(idx);  // <-- ERROR

Error logs:
