I'm using the Youtube V3 API nuget package for C#, and I am experiencing a JSON issue when Retrieving the contentDetails part of the channel resource.
Is there currently a bug in the API causing server side 500 errors?
Here is my code for the implementation.The error is happening when I call this line of code:
var channelsListResponse = await channelsListRequest.ExecuteAsync();
public async Task<IEnumerable<Snippet>> GetAllAsync() { var videoList = new List<Snippet>(); // Create the service var service = new YouTubeService(new BaseClientService.Initializer { ApplicationName = this.GetType().ToString(), ApiKey = _apiKey }); var channelsListRequest = service.Channels.List("contentDetails"); channelsListRequest.Mine = true; // Retrieve the contentDetails part of the channel resource for the authenticated user's channel. var channelsListResponse = await channelsListRequest.ExecuteAsync(); foreach (var channel in channelsListResponse.Items) { // From the API response, extract the playlist ID that identifies the list // of videos uploaded to the authenticated user's channel. var uploadsListId = channel.ContentDetails.RelatedPlaylists.Uploads; var nextPageToken = ""; while (nextPageToken != null) { var playlistItemsListRequest = service.PlaylistItems.List("snippet"); playlistItemsListRequest.PlaylistId = uploadsListId; playlistItemsListRequest.MaxResults = 50; playlistItemsListRequest.PageToken = nextPageToken; // Retrieve the list of videos uploaded to the authenticated user's channel. var playlistItemsListResponse = await playlistItemsListRequest.ExecuteAsync(); foreach (var playlistItem in playlistItemsListResponse.Items) { // Print information about each video. // Console.WriteLine("{0} ({1})", playlistItem.Snippet.Title, playlistItem.Snippet.ResourceId.VideoId); videoList.Add(new Snippet() { Title = playlistItem.Snippet.Title }); } nextPageToken = playlistItemsListResponse.NextPageToken; } } return videoList; }Here is the result of running the method using a controller and postman...
I am using a snippet I found on the Youtube API documentation for samples.
