This interaction has already been acknowledged-CodePudding

I'm creating a discord bot that I use multi-threading to update an ArrayList every few minutes. The first 'update' works correctly with no error, though every update afterwards I get the error:

[JDA MainWS-ReadThread] ERROR RestAction - RestAction queue returned failure
java.lang.IllegalStateException: This interaction has already been acknowledgdge an interaction once!

I'm creating the threads in Multithread.java which says:

public static void main(String[] args) throws InterruptedException {
        // Create a new bot
        Thread startApp = new Thread(new App());
        
        // Start the thread
        startApp.start();

        // Create new thread for updating
        new App();
        Thread updateTeams  = new Thread(App.updateAll());
        updateTeams.start();

    }

The ArrayList that i'm updating (OCETeams) is in App.java and is public and static.

In App.java, I have the following methods that relate to this:

    @Override
    public void run() {
        try {
            System.out.println("Starting.............");
            initialize();
        } catch (LoginException | ParseException | InterruptedException e) {
            e.printStackTrace();
        }
    }

    // For the 'updating' thread    
    public static Runnable updateAll() {
        Timer timer = new Timer();
        timer.schedule(new TimerTask() {
            @Override
            public void run() {
                try {
                    System.out.println("Updating all");
                    OCETeams = getOCETeams();
                    System.out.println("OCE teams updated");
                } catch (ParseException e) {
                    e.printStackTrace();
                }
            }
            
        } , 0, 60000 * 20);

        return null;
    }

In essence you have already replied for example and you are trying to reply again which throws the error and there is not enough info from the code you provided.
