'How to Direct Message a specific person with a Discord Bot

I have tried to DM myself using the code:

User me = new UserById(myId);
me.openPrivateChannel().flatMap(channel -> channel.sendMessage("hello")).queue();

This results in an error message:

[JDA MainWS-ReadThread] ERROR JDA - One of the EventListeners had an uncaught exception

I have looked everywhere, but can't find an answer.

Solution 1:[1]

You can use event.getJDA().getUserById() like

User user = event.getJDA().getUserById(id);
user.openPrivateChannel().flatMap(channel -> channel.sendMessage("hlo")).queue();

Also, keep in mind that this would not work if you and your bot do not have a common server or if you have DMs by server members disabled.
