Solved Help With Plugin Coding onDeath Event

So anyways, I am trying to make a custom plugin for my server that does everything however I am getting issues with the onDeath event. Everything is working perfectly fine in game, but on the console, I get an error whenever a player dies in anyway except for 1 player killing another player. This is more a behind the scenes thing since everything is working fine in game how I would like it to, however the errors are not good. I been searching online for a solution for like 6 hours. I have 2 classes, a main and a listener so I will give you the code.
Main Class:

Code:
