Error deserializing JSON (JSON array)

Question

I looked for other topics related to this error, but I believe my case is a little different.

Error:

System.Exception: Error processing request: Cannot deserialize the Current JSON array (e.g. [1,2,3]) into type 'Models.Request' because the type requires a JSON Object (e.g. {"name":"value"}) to deserialize correctly. To fix this error either change the JSON to a JSON Object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that Implements a Collection interface (e.g. Icollection, Ilist) like List that can be deserialized from a JSON array. Jsonarrayattribute can also be Added to the type to force it to deserialize from a JSON array. Path '', line 1, position 1.

Let’s go from the top:

I am trying to perform a POST and getting this error in the application. This error no longer makes sense, because in the post I do not perform any deserialization.

Testing on a Motorola Z3 Play.

Code that generates the error: ("client" is an instance of Httpclient() )

public async Task AddPedidoAsync(Pedido pedido)
        {
            try
            {
                string url = "http://<endereço>:55580/api/Pedidos";
                string token = Preferences.Get("token", "default_value");
                client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", token);
                var data = JsonConvert.SerializeObject(pedido);
                StringContent content = new StringContent(data, Encoding.UTF8, "application/json");
                HttpResponseMessage response = null;
                response = await client.PostAsync(url, content);
                if (!response.IsSuccessStatusCode)
                {
                    throw new Exception("Erro ao incluir pedido");
                }
            }
            catch (Exception ex)
            {
                throw new Exception("Erro na solicitação: " + ex.Message);
            }

The class "requested":

public class Pedido
{
    public int Id { get; set; }
    public int IdEstabelecimento { get; set; }
    public int IdCliente { get; set; }
    public int IdStatus { get; set; }
    public int IdFormaPagamento { get; set; }
    public DateTime DataPedido { get; set; }
    public decimal ValorTotal { get; set; }
    public decimal ValorDesconto { get; set; }
    public decimal ValorEntrega { get; set; }
    public decimal ValorTroco { get; set; }
    public bool Recepcionado { get; set; }
    public DateTime? DataRecepcao { get; set; }
    public int IdPedidoMobile { get; set; }
}

What I’ve already tested:

When debugging, initially I thought the error could be due to the structure of my JSON with regard to the "Requested Datafield", which is a Datetime:

{\"Id\":0,
\"IdEstabelecimento\":1,
\"IdCliente\":1,
\"IdStatus\":1,
\"IdFormaPagamento\":1,
\"DataPedido\":\"2019-01-29T10:40:52.539523-02:00\",
\"ValorTotal\":220.99,
\"ValorDesconto\":0.0,
\"ValorEntrega\":0.0,
\"ValorTroco\":0.0,
\"Recepcionado\":false,
\"DataRecepcao\":null,
\"IdPedidoMobile\":2975}

So I changed my Order class and converted the date to the format without the milliseconds. Nothing done.

To conclude in a very strange way:

If I query in my database, the request was posted correctly!
