The console said that my protocole manager is null. Do you know why?

I'm using the lastest build for version 1.18

I'm trying to add a listener on particules packets

Here's my code:
`@Override
public void onEnable() {

    instance = this;
    protocolManager = ProtocolLibrary.getProtocolManager();

    protocolManager.addPacketListener(
    new PacketAdapter(this, ListenerPriority.NORMAL,
            PacketType.Play.Server.WORLD_PARTICLES) {
        @Override
        public void onPacketSending(PacketEvent event) {

            System.out.println(event.getPlayer().getName() + " est le joueur en question: " + event.getPlayer().getUniqueId());

            // Item packets (id: 0x29)
            if (event.getPacketType() ==
                    PacketType.Play.Server.WORLD_PARTICLES && event.getPlayer().getUniqueId() == UUID.fromString("f1786fc3-9795-415a-a9c0-8538fd69fae8")) {
                System.out.println(event.getPacketType().name());
                event.setCancelled(true);
            }
        }
    });

    System.out.println("PacketParticule");

}`

I have the same issue

ProtocolManager manager = ProtocolLibrary.getProtocolManager();

if (manager != null) {
    manager.addPacketListener(new PacketAdapter(plugin, ListenerPriority.NORMAL, PacketType.Play.Client.ARM_ANIMATION) {
        @Override
        public void onPacketReceiving(PacketEvent event) {
            super.onPacketReceiving(event);
            onPlayerBreakStateChanges(event);
        }
    });
}

Code above is inside onEnable and ProtocolLib is provided as a hard dependency.

Please ensure that you haven't shaded protocol lib into your plugin then...

Can you provide us the stacktrace and more background information, like if you're depending on ProtocolLib etc?

or where this code is called. for example, if it's in onLoad, you might not have access to the protocol manager. or in onEnable, you may not be properly depending on PL

Another thing that came to my mind is that you're shading protocol lib into your plugin - don't do that. Put the plugin onto your server directly and depend on it.

Check your pom.xml, make sure the scope is provided
