Config return Nullpointer

Hi, I have been trying to fix this problem on my own but just couldn't do it.

I am getting a NullPointerException

Code:

at line 303 in my secondary class and I know that it must be because of incorrect initialization but I just can't figure outhow to do it.

Code:java

    FileConfiguration config = plugin2.getConfig();

my initialization:

Code:java

WinterSlashMain plugin2;
 
    public WinterSlashManager(WinterSlashMain instance) {
    plugin2 = instance;
    }

Thank you!

 

Post the full class.

How about the class where you initialize this class?

 

I went through my classes and realized I haven't actually initialized the config in my main class. How would I go about doing it?
