Solved PlayerInteract Error

So I get a console error everytime I leftclick and right click a block. here is my code:

Code:

    @EventHandler
    @SuppressWarnings("static-access")
    public void onPlayerInteract(PlayerInteractEvent event) {

        Action Action = event.getAction();

        if ((Action == Action.PHYSICAL) || (event.getItem() == null)
                || (event.getItem().getType() == Material.AIR)){
            return;
        }
        // JOIN CLICK DO =====================================
        if (event.getItem().getType() == Material.NETHER_STAR) {
            JoinGUI.openGUI(event.getPlayer());
            return;

HERE IS ERROR:

Code:

Moved to Alternatives Section.

 

@malikdbuseck That snippet has nothing to do with your stack-trace. Check if the Block's type is a sign before casting the Block's state to Sign.

 

Wow Im so stupid. Should read that error more throughly. But here is the fix for anyone else

if(event.getClickedBlock().getType() != Material.SIGN)return;
