Solved p.getEyeLocation().getBlock()

Hello, a question someone could tell me is I'm doing wrong, looking at the chest and open it does not work

Code (Text):

      @EventHandler
      public void onShifAndLeftClick(PlayerInteractEvent event) {
          Player p = event.getPlayer();
          if(p.isSneaking() && event.getClickedBlock().getType() == Material.CHEST && event.getAction() == Action.RIGHT_CLICK_BLOCK)
        {                          
              Chest(p, p.getEyeLocation().getBlock()); //error//
               p.sendMessage(color("&cNice"));
        }
      }
     
      public void Chest(Player p,Block block) {
            block.getType();
            final Chest chest = (Chest)block.getState();
           Inventory inv = chest.getInventory();
           ItemStack one = new ItemStack(Material.DIAMOND);
           inv.addItem(one);
      }      

Spoiler: Error console
