Solved NPE on if statement

this is the line its referring to, yes the file exists and is there

Code:

if(!(mainClass.raceConfig.contains(p.getUniqueId().toString())))
 {
         mainClass.raceConfig.set(p.getUniqueId().toString(), "Elf");
         try {
         mainClass.raceConfig.save(mainClass.raceFile);
         mainClass.raceConfig.load(mainClass.raceFile);
         } catch (IOException | InvalidConfigurationException e1) {
                  e1.printStackTrace();
         }
         p.sendMessage(ChatColor.AQUA + "You chose the race of Elf");
         p.closeInventory();
}

 

I suggest to make your code more readable in terms of understanding and debugging.
What I mean is split up your code for example:

Code:

p.getUniqueID().toString()

will become

Code:

ID id = p.getUniqueID();
idAsString = id.toString();

if you continue doing this on your code it will become cleaner and more understandable and you can view your variables and values in a debugger or print the values to the console to see which statement gives you a NullPointer.

Alright but the exact line that im getting an error in is the
if(!(mainClass.raceConfig.contains(p.getUniqueId().toString())))
the config file exists its in my plugin folder, the player exists because its on an inventory event click so I don't know what could be giving null

 

Post the NPE stack trace
