Version of JDA

5.0.0-beta.21

Expected Behaviour

Register command for a special guild

Code Example for Reproduction Steps

Guild guild = jda.getGuildById("1225815657883373578");
        guild.updateCommands().addCommands(Commands.slash("test", "Ja ist halt ein Test näh?"));

Code for JDABuilder or DefaultShardManagerBuilder used

JDA jda = JDABuilder.createDefault("Why")

Exception or Error

guild is null. You're probably using jda when it has empty cache. If you will do jda.awaitReady() it will block and wait until JDA populates cache. Then jda.getGuildById(id) wont return null. Also you forgot .queue() on CommandListUpdateAction :) More info: https://docs.jda.wiki/net/dv8tion/jda/api/entities/Guild.html#updateCommands()
