How should I handle replies to messages that are too long?

I tried splitting up replies into chunks of 2000 chars (that's the limit for each message), but it didn't work:

(the variable string is the response, by the way)

                            if(string != null) {
                                if(string.length() > 2000) {
                                    // split into chunks of 2000
                                    List<String> strings = new ArrayList<String>();
                                    int index = 0;
                                    int chunks = 2000;
                                    while (index < string.length()) {
                                        strings.add(string.substring(index, Math.min(index + chunks, string.length())));
                                        index += chunks;
                                    }

                                    for(String s : strings) {
                                        message.reply(string); // I know for a fact that `string` is set correctly and that the code to split messages into chunks is working. It is a problem with message.reply(string).
                                    }
                                } else*/
                                    message.reply(string);
                            }

There's no output or exceptions. No messages sent on discord. No nothing. It simply just does not work. I tried putting a Thread.sleep(1000) after the message.reply(string) to see if maybe a delay would work, but nope. I also tried making the message chunks 500 chars long, but that didn't work either. Honestly, I have no idea what to say.

And without the code to split it into chunks, it also produces no output.

Message#reply() returns a future.
Check if message.reply(string).get() throws an exception.
