Solved [Help] Name can not be null...

Hello everyone!
I am currently working on a mini-game plugin and have run into a little problem... I am trying to make randomized spawn points for respawn location but keep getting this dumb error!
Error:

My Arena Method that is SUPPOSE to load and add the spawn points:

Code:java

 ArrayList<Location> spawns = new ArrayList<Location>();
public void registerSpawns(){
for(String loc : Main.getInstance().getConfig().getKeys(false)){
int x, y, z;
float pitch, yaw;
String world;
if(loc == null) return;
x = Main.getInstance().getConfig().getInt(loc + ".x");
y = Main.getInstance().getConfig().getInt(loc + ".y");
z = Main.getInstance().getConfig().getInt(loc + ".z");
pitch = Main.getInstance().getConfig().getInt(loc + ".pitch");
yaw = Main.getInstance().getConfig().getInt(loc + ".yaw");
world = (String) Main.getInstance().getConfig().getString(loc + ".world");
Location add = new Location(Bukkit.getWorld(world), x, y, z);
add.setPitch(pitch);
add.setY(yaw);
spawns.add(add);
}
System.out.println("[WARRIOR] + " + spawns.size() + " random spawn points have been found!");
}

Configuration File:

Code:

randomspawn1:
  x: -466
  y: 30
  z: -1614
  yaw: 1.2004395
  pitch: 14.699967
  world: Lobby
randomspawn2:
  x: -458
  y: 30
  z: -1584
  yaw: 140.09998
  pitch: 10.649981
  world: Lobby
randomspawn3:
  x: -476
  y: 30
  z: -1588
  yaw: 188.54999
  pitch: 8.699981
  world: Lobby

EDIT: Added what my configuration file looks like.
EDIT: I tried getKeys(true) as-well but I get the same error :l

If you guys need anymore code in order to help me solve this please ask!
Thank you for reading!
All help is much appreciated!

 

We need to see your main class:
at me.XvPROTECTEDvX.Main.Main.onEnable(Main.java:44) ~[?:?]

 

Its just:

Code:java

Arena.getManager().registerSpawns();

I just call the method to load the spawns.

I fixed it :3 Solved!
