定期错误：Newtonsoft.Json.JsonReaderException：从JsonReader读取JObject时出错。路径''，第0行，位置0

Question

我正在使用自动化测试，并定期看到此错误，该错误未能通过其中一项测试

Newtonsoft.Json.JsonReaderException : Error reading JObject from JsonReader. Path '', line 0, position 0.
TearDown : Newtonsoft.Json.JsonReaderException : Error reading JObject from JsonReader. Path '', line 0, position 0.
   at Newtonsoft.Json.Linq.JObject.Load(JsonReader reader, JsonLoadSettings settings)
   at Newtonsoft.Json.Linq.JObject.Parse(String json, JsonLoadSettings settings)
   at Project.Command.User.WebApi.SessionWebApiData.UpdateUserAndDealer()
   at Project.FuncTests.Rock.ROCKTests.TestUserCanDownloadApprovedHtmlBannerTransaction() in <path>\ROCKTests.cs:line 652
--TearDown
   at Newtonsoft.Json.Linq.JObject.Load(JsonReader reader, JsonLoadSettings settings)

   at Project.FuncTests.Base.TestSetup.TearDown() in <Path>\Base\TestSetup.cs:line 139

我不明白为什么它有时会起作用 我是Newtonsoft.Json的最新版本

有代码：

internal static void UpdateUserAndDealer()
{
    var sessionDealerAndUserJson = AjaxRequest.Create("GET", $"{Support.BaseUrl}WebAPI/api/Retailer/GetSessionDealerAndUser");
    sessionDealerAndUserJson.Send();
    var dealerAndUserJO = JObject.Parse(sessionDealerAndUserJson.Response);
    //var dealerAndUserJO = JsonConvert.DeserializeObject(sessionDealerAndUserJson.Response);
    Dealer = dealerAndUserJO["DealerInfo"].ToObject<DealerDto>();
    User = dealerAndUserJO["UserInfo"].ToObject<UserDto>();

    var cultureJson = AjaxRequest.Create("GET", $"{Support.BaseUrl}WebAPI/api/culture");
    cultureJson.Send();
    Cultures = JsonConvert.DeserializeObject<List<CultureDto>>(cultureJson.Response);
    Currency = Cultures.Find(x => x.Name.Equals(User.CultureName)).CurrencySymbol;
}
