Spigot 1.16 InventoryClickListener

I have a problem with my InventoryClickListener it works fine, but everytime a Player swaps an Item in his inventory its printing an error code. To fix that I made this if-statement but it seems to not work

Code:

if(event.getView().getType().equals(player.getInventory().getType())) {
              return;
          }

I worked with 1.8 Spigot before, so I don´t know if there are any other solutions in the 1.16 Spigot for my problem.

@timtower help me please

Show the error and the code.

It'd have been better had you not cropped the file; now we have no way of correlating the HB line numbers to the real line numbers to know what line is 39. Which is it?

 

listener(39) = hastebin(19)


String name = item.getItemMeta().getDisplayName();

 

@MiBB3L itemMeta of the item is null. Replace hasItemMeta with getItemMeta == null in your checks.
