    Hello Bukkit community. I am in need of some assistance. For some reason, my PlayerInteractEvent is always throwing the same error all the time. I tried multiple ways to resolve the issue. All of which have failed. Please help me out.

    Error:

    Probably openGUI(), which he probably needs to call in his onEnable()

    Code:
        at me.surferdude999.hubmenu.Main.openGUI(Main.java:80) ~[?:?]
    at me.surferdude999.hubmenu.Main.onPlayerInteract(Main.java:146) ~[?:?]
    Line 146 is hi openGUI thing in the PlayerInteractEvent.
    The error occurs in the openGUI class, not the PlayerInteract.
    Could you show your openGUI code?

    It's not a new class.

    openGUI is a method within the Main class.

    But yes, as the others say, we need to know the code so we can help you.

    You might as well post the entire Main class.
