Hey I'm getting this error from the ProtocolManager idk why this happens

Error:

@Override
    public void onEnable() {
        System.out.println(ProtocolLibrary.getProtocolManager().getMinecraftVersion().toString());
        protocolManager = ProtocolLibrary.getProtocolManager();
}

The protocolManager is always null

ProtocolLib Version: 5.0.0

typically this happens either when you don't declare PL as a dependency in your plugin yml or if you're shading PL into your jar

So in your case, try adding <scope>provided</scope> to the ProtocolLib dependency
