An error thrown in the official nuget sdk example code

ILogger logger = NullLogger.Instance;CancellationToken cancellationToken = CancellationToken.None;SourceCacheContext cache = new SourceCacheContext();SourceRepository repository = Repository.Factory.GetCoreV3("https://api.nuget.org/v3/index.json");PackageMetadataResource resource = await repository.GetResourceAsync<PackageMetadataResource>();IEnumerable<IPackageSearchMetadata> packages = await resource.GetMetadataAsync("Newtonsoft.Json",    includePrerelease: true,    includeUnlisted: false,    cache,    logger,    cancellationToken);foreach (IPackageSearchMetadata package in packages){    Console.WriteLine($"Version: {package.Identity.Version}");    Console.WriteLine($"Listed: {package.IsListed}");    Console.WriteLine($"Tags: {package.Tags}");    Console.WriteLine($"Description: {package.Description}");}

This code is written in C#. The logger attribute inside the IEnumerable throws an error. Also, and more important it gets stuck on the first line of code with await:

PackageMetadataResource resource = await repository.GetResourceAsync<PackageMetadataResource>();

It gets there, but the await never closes.

Does anyone knows how to fix this? Did anyone have this problem before?

This is the official SDK link: https://learn.microsoft.com/en-us/nuget/reference/nuget-client-sdk

I want to solve the problems so it does not get stuck and returns the expected example output
