Custom event triggering EventException when calling event

I should mention I do get the message "It's not null dafuq?"... Also the try catch block actually doesn't catch the exception so that's why I'm having a hard time debugging this...

PHP:

                    //Call Event
                    CustomPlayerChatEvent customEvent = new
                            CustomPlayerChatEvent(ChatColor.translateAlternateColorCodes('&', message), evt.getPlayer(),
                            chatAdminPrefixStart+prefix, suffix);
                    /**/
                    Player developer = Bukkit.getPlayer("TheWolfBadgerDev");
                    if(customEvent == null) {
                        developer.sendMessage("It's null oddly?");
                    } else {
                        developer.sendMessage("It's not null dafuq?");
                    }
                    try {
                        Bukkit.getServer().getPluginManager().callEvent(customEvent); //This is the line the error gives
                    } catch (Exception ex) {
                        developer.sendMessage(ex.getMessage());
                    }

Error:
