Cannot deserialize the current JSON array into type model because the type requires a JSON object to deserialize correctly

Question

I am working on consuming web api's from asp.net web applications and now I have this trouble. I am using my web api just to retrieve data from my db and for it's security with jwt. On the other hand, I have this mvc web application which consumes this web api. When I run my web-api, it's all okay, I can easily retrieve the data that I want, but it's not happening the same from my web app. Can someone please help me get familiar with serializing and why it's not reading the data from my db ? The error is popping up when the breakpoint reaches at the " readTask.Wait(); " line.

This is my WebApi controller:

public IHttpActionResult GetById (string id)
{
    ConnectionString();
    con.Open();
    SqlCommand com = new SqlCommand("oid_validation", con);
    com.CommandType = CommandType.StoredProcedure;
    com.Parameters.Add(new SqlParameter("@oid", id));
    SqlDataReader dr = com.ExecuteReader();
    DataTable dt = new DataTable();
    dt.Load(dr);
    dt.TableName = "mytable";
    return Ok(dt);
}

This is my model class and it is the same one on both my api and my web app.

public class v_websearch 
{
public system.guid ID {get; set;}
public system.DateTime DateSale {get; set;}
public system.DateTime From {get; set;}
public system.DateTime To {get; set;}
}

This is my web app controller used for consuming api's data:

    public async Task<ActionResult> Confirm(string id)
    {
                var token = (string)Session["access_token"];
                V_WebSearch dt = null;
                using (var client2 = new HttpClient())
                {
                    client2.BaseAddress = new Uri("http://localhost:63443/api/");
                    client2.DefaultRequestHeaders.Add("Authorization", $"Bearer {token}");
                    var responseTask = client2.GetAsync("default/" + id);

                    var result = responseTask.Result;

                    #region Error Handlers
                    if (result.IsSuccessStatusCode)
                    {
                        var readTask = result.Content.ReadAsAsync<V_WebSearch>();
                        readTask.Wait();
                        dt = readTask.Result;
                        return View(dt);
                    }
               }
      }

I like SOLID principles! xD.

• You can see Http response of GetById (review the json response) it doesn't seem to be how you expect.

• ForHttpClient try GetFromJsonAsync Method.
