Why do I get an error when I try to click outside the inventory / in the inventory where there's no item

Question

I am using Spigot 1.14 and when I try to click in the inventory or outside the inventory where there is no item I get an error.

I have tried with different methods such as:

e.getCurrentItem().getItemMeta().getDisplayName()
e.getCurrentItem().getItemMeta().hasDisplayName()

and some other methods but none of them seem to work.

if (e.getCurrentItem().getItemMeta().getDisplayName() != null && (e.getCurrentItem().getItemMeta().getDisplayName().equalsIgnoreCase("§eMystery Box"))) {

When I click outside the inventory or in the inventory where there is no item I get this error message: https://pastebin.com/v0wDB2gp

Saying that it could not pass the inventory click event.

You need to post your full `clickevent` class, or if it's too big then only post the problematic method, around line 23 — Noel Nemeth, Jul 31 '19 at 10:53

From the code and the stacktrace everything I can say is that either e.getCurrentItem().getItemMeta() or e.getCurrentItem() is returning null.
Stacktrace
