c# - 我如何找到 RestSharp PUT 抛出异常的原因？

Question

我已经发送了 PUT请求并得到 NullReferenceException在RestSharp.Portable :

using (var client = new RestClient(new Uri(BaseUri)))
{
    var oAuth1Authenticator = OAuth1Authenticator.ForAccessToken(
      OAuthConsumerKey,
      OAuthConsumerSecret,
      oAuthToken", 
      oAuthSecret"
    );

    client.Authenticator = oAuth1Authenticator;

    var request = new RestRequest(lastPartUri, httpMethod);

    request.AddJsonBody(body);

    IRestResponse response = await client.Execute(request);

    return response.Content;
}

线路IRestResponse response = await client.Execute(request);抛出异常。

OAuth 参数绝对不是 null ，都不是BaseUri和lastPartUri 。 body是 Dictionary<string, string>并且也不为空。

POST和GET具有相同参数的请求工作得很好。

看起来问题出在RestSharp图书馆。我怎样才能找到它？

这是堆栈跟踪:

这确实是库中的一个错误。开发者已经修复。
