About ArrayIndexOutOfBoundsException in chatgames.yml

[M-WhiteXFox]

If I remove the contents of chatgames.yml/Rewards in quotes, but leave the quotes in, it may raise an error

My TChat version is 4.3.1

Here’s an example from the chatgames.yml file

    rewards:
      - ""

It will cause an error to be reported

I believe the cause of this error is in the executeRewards method at line 302 in ChatGamesSender.java. The check currentGame.getRewards() != null verifies whether it is not null, but it does not ensure that it contains any content.

    private void executeRewards(Player player) {
        if (currentGame.getRewards() != null) {
            for (String reward : currentGame.getRewards()) {
                final String command = reward.replace("%winner%", player.getName());
                Bukkit.getScheduler().runTask(plugin, () -> {
                    Bukkit.dispatchCommand(Bukkit.getConsoleSender(), command);
                });
            }
        }
    }
