getting Internal Server Error when call a Web API by async

Question

I have created an Web API application.

This application I have hosted on one server.

 

Now I am calling a post method of that (hosted ) application using async call in another application, so If I put a debugger then I am getting an Internal Server Error when call a Web API by async.

Bellow is my code

public async void PostRequest(string name)

{

try

{

string name = "rupesh";

Uri requestUri = new Uri("http://xxxxx:2565/api/Registration/SignUp"); //replace your Url

string json = "";

json = Newtonsoft.Json.JsonConvert.SerializeObject(name);

var objClint = new System.Net.Http.HttpClient();

System.Net.Http.HttpResponseMessage respon = await objClint.PostAsync(requestUri, new StringContent(json, System.Text.Encoding.UTF8, "application/json"));

string responJsonText = await respon.Content.ReadAsStringAsync();

}

catch (Exception ex)

{

var er = ex.Message.ToString();

}

}

 

Give me some solution.

Thanks
