#TaskCanceledException, Command code not executing

I'm attempting to build a discord bot using Commands, and while the commands are registering (I can see them in autocomplete), I'm seeing this exception rather regularly:

System.Threading.Tasks.TaskCanceledException: A task was canceled.
  at DSharpPlus.Net.Gateway.GatewayClient.HandleEventsAsync(CancellationToken ct) : A task was canceled.
  at DSharpPlus.Net.Gateway.GatewayClient.HandleEventsAsync(CancellationToken ct)```
I don't see any other errors in the logs, but attempting to use my commands results in "the application did not respond", and setting a breakpoint in the command results in the breakpoint not being hit, making me think this error is preventing the bot from receiving commands.
# 
        {
            string token = ConfigHelper.Current.Token;
            DiscordClientBuilder builder = DiscordClientBuilder.CreateDefault(token, DiscordIntents.AllUnprivileged | DiscordIntents.MessageContents);

            builder.UseCommands(
                extension =>
                {
                    extension.AddCommands([typeof(Commands.RegistrationCommands)]);
                },
                new CommandsConfiguration()
                {
                    DebugGuildId = 0,
                    RegisterDefaultCommandProcessors = true,
                    UseDefaultCommandErrorHandler = false
                });

            DiscordClient client = builder.Build();

            DiscordActivity status = new DiscordActivity("with itself", DiscordActivityType.Playing);

            await client.ConnectAsync(status, DiscordUserStatus.Online);

            while (!stoppingToken.IsCancellationRequested)
            {
                await Task.Delay(5000, stoppingToken);
            }
        }```
# 
    class RegistrationCommands
    {
        [Command("add")]
        public static ValueTask AddAsync(CommandContext context)
        {
            return context.RespondAsync("Still not implemented");
        }

        [Command("remove")]
        public static ValueTask RemoveAsync(CommandContext context)
        {
            return context.RespondAsync("This isn't implemented either");
        }
    }```

I don't know what I'm missing or getting wrong, but maybe someone else can spot it?

What does your program.cs look like?

# 
builder.Services.AddHostedService<Worker>();

IConfiguration configuration = builder.Configuration;

ConfigHelper.Current = new ConfigHelper(configKey => configuration.GetValue<string>(configKey));

var host = builder.Build();
host.Run();

Its likely not fixing your bug but in this case where you have a generic host setup please use the methods on the service collection to build the client instead of using the builder

#

I rewrote the application to use the service collector to build the client, and got the same results (as expected), but along the way noticed something interesting: if I remove DiscordIntents.MessageContents when setting up the discord client, the error goes away, and my bot works as expected (with slash commands).

Oh do you enabled that intent in the dashboard? Its a privileged intent you have to request

radiant fractal
#

They make the dashboard nice and confusing to follow; is that the permissions I select when I created the discord invite link?

dire flower
#

Its under the bot section

#

Ah! I missed that one; that would be the cause!

I think it's another instance of ##2046
