Trying to deal with twitch.API, making examples of this library

Rechecked Token (created via twitch token generator, with all permissions), idClient c dev.twitch

The function of checking a user for a subscription to the channel works correctly (which uses all the same IDs as the other functions, so that they are exactly correct), but all the others give one of two errors shown in the screenshots.

Need ideas with what it can be connected

enter image description here enter image description here

public TwitchBot() { connectionCredentials = new ConnectionCredentials(TwitchInfo.BotName, TwitchInfo.AccessToken); random = new Random(); CreateCommands(); Connection(); var channelInfo = new TwitchLib.Api.Models.v5.Channels.Channel(); twitchAPI = new TwitchLib.Api.TwitchAPI(); twitchAPI.Settings.ClientId = TwitchInfo.ClientId; twitchAPI.Settings.AccessToken = TwitchInfo.AccessToken; DisplayResultAsync(); } static async void DisplayResultAsync() { await ExampleCallsAsync(); } void Connection() { twitchClient = new TwitchClient(); twitchClient.Initialize(connectionCredentials, TwitchInfo.Channel); twitchClient.OnMessageReceived += TwitchClient_OnMessageReceived; twitchClient.OnWhisperReceived += TwitchClient_OnWhisperReceived; twitchClient.OnUserJoined += TwitchClient_OnUserJoined; twitchClient.OnChatCommandReceived += TwitchClient_OnChatCommandReceived; twitchClient.Connect(); } private static async Task ExampleCallsAsync() { //Checks subscription for a specific user and the channel specified. Subscription subscription = await twitchAPI.Channels.v5.CheckChannelSubscriptionByUserAsync(TwitchInfo.Channel, "stribog45"); //Gets a list of all the subscritions of the specified channel. //var allSubscriptions = await twitchAPI.Channels.v5.GetAllSubscribersAsync(TwitchInfo.Channel); //Get channels a specified user follows. //GetUsersFollowsResponse userFollows = await twitchAPI.Users.helix.GetUsersFollowsAsync("stribog45"); //Get Spedicified Channel Follows //var channelFollowers = await twitchAPI.Channels.v5.GetChannelFollowersAsync(TwitchInfo.ClientId); //Return bool if channel is online/offline. bool isStreaming = await twitchAPI.Streams.v5.BroadcasterOnlineAsync(TwitchInfo.Channel); //Update Channel Title/Game //await twitchAPI.Channels.v5.UpdateChannelAsync("channel_id", "New stream title", "Stronghold Crusader"); }
