Discord.NET DiscordRestClient 401 Unauthorized

Question

I'm using Discord.Net v3.5.0.

I have an OAuth2 Access Token and I'm trying to use a DiscordRestClient to get the user's guilds, but I'm getting back 401 Unauthorized.

DiscordRestClient discordClient = new();
await discordClient.LoginAsync(TokenType.Bearer, accessToken);
IReadOnlyCollection<IGuild> restGuilds = await discordClient.GetGuildsAsync();

Stepping over await discordClient.GetGuildsAsync() throws the exception.

fail: Microsoft.AspNetCore.Components.Server.Circuits.CircuitHost[111]
      Unhandled exception in circuit 'iPxGWxw_tZW73Ya4zYXPehZr3w_Wdcs9uXYuEaUkslY'.
      Discord.Net.HttpException: The server responded with error 401: 401: Unauthorized
         at Discord.Net.Queue.RequestBucket.SendAsync(RestRequest request)
         at Discord.Net.Queue.RequestQueue.SendAsync(RestRequest request)
         at Discord.API.DiscordRestApiClient.SendInternalAsync(String method, String endpoint, RestRequest request)
         at Discord.API.DiscordRestApiClient.SendAsync[TResponse](String method, String endpoint, BucketId bucketId, ClientBucketType clientBucket, RequestOptions options)
         at Discord.API.DiscordRestApiClient.GetGuildAsync(UInt64 guildId, Boolean withCounts, RequestOptions options)
         at Discord.Rest.ClientHelper.GetGuildsAsync(BaseDiscordClient client, Boolean withCounts, RequestOptions options)

I can successfully use a regular HttpClient though, so I can confirm the Access Token is valid.

HttpClient httpClient = httpClientFactory.CreateClient();
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
JsonArray? myGuilds = await httpClient.GetFromJsonAsync<JsonArray>("https://discord.com/api/v9/users/@me/guilds");

What am I doing wrong?

You are not initialize DiscordRestClient proberly.

DiscordRestClient discordClient = new();

Initializes a new DiscordRestClient with the provided configuration.
