我怎样才能找到为什么RestSharp PUT抛出异常？

Question

我已发送了PUT个请求并在NullReferenceException中获得了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;
}

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

OAuth参数绝对不是null，BaseUri和lastPartUri也不是body。 Dictionary<string, string>是POST，也不是空。

具有相同参数的

GET和RestSharp请求可以正常工作。

这是堆栈跟踪：

这确实是图书馆中的一个错误。开发人员已经修好了。
