    This is the error i get by this code:

    Code:java
    1.     @EventHandler
    2.     public void sign(PlayerInteractEvent e){
    3.         if(!(e.getClickedBlock().getState() instanceof Sign)) return; //this is line 71
    4.         if (e.getClickedBlock().getState() instanceof Sign) {
    5.             Sign s = (Sign) e.getClickedBlock().getState();
    6.             if(ChatColor.stripColor(s.getLine(0)).equals("Kit Selection")){
    7.                 Gui.openKitGui(e.getPlayer());           
    8.         }   
    9.     }
    10.     }

    The error occurs only when the interacting player has a block/item in had. Else works just fine, What is the condition i should add?
    Thanks a lot.

    getClickedBlock() can be null, do a null-check.

    The clicked block can be null, add a null check to avoid that

    Remember players can interact with stuff other than blocks.
