This is the part of function I wrote to rename a voice channel in order to show my Minecraft server’s online status with voice channel name

    public static void changeName(String online) {


        Guild guild = jda.getGuildById("1122886719126126682");

        VoiceChannel channel = guild.getVoiceChannelById("1147195002603184159");

       channel.getManager().setName(online).queue(

                success -> System.out.println("Successfully renamed to: " + online),
                error -> System.out.println("Failed to rename: " + error.getMessage())

        );
    }

And I got this error (p.s. there are some other printed lines are from other parts of code)

I was trying to use this code to rename a voice channel, but it just doesn’t work
