Internal Server Error 500 when using Web Api Http Put

Question

I'm developing a Webapp to a company that use Picking Process.

The process is very simple, I have a sales order with some information, and i creating a picking list with some of that information (for example: number of items, total weight, and id of sales order).

I'm getting always this error

Internal Server Error

...when I'm trying to use PUT method, to create a Picking List and add it into a database in Web Api side.

When I remove [HttpPost] the error change to :

Method Not Found

or

Method Not Allowed

This is my code:

Client Side

public async Task AddTarefa(ListasPicking listaPickingAdd) 
{
    String listaparaAdicionar = listaPickingAdd.idLista + ";" + listaPickingAdd.IDordemVenda + ";" + listaPickingAdd.peso + ";" + listaPickingAdd.itens;
    HttpResponseMessage response = await cliente.PutAsJsonAsync("api/ListasPicking/", listaparaAdicionar);

    return response.IsSuccessStatusCode;
}

Web Api Side - Controllers

//PUT: api/ListasPicking
[ResponseType(typeof (ListasPicking))]
[HttpPut]
public  IHttpActionResult PutLista ([FromBody] String lista)
{
    if(!ModelState.IsValid)
    {
        return BadRequest(ModelState);
    }

    String[] result = lista.Split(';');
    ListasPicking novaLista = new ListasPicking();
    novaLista.idLista=result[0];
    novaLista.IDordemVenda = result[1];
    string lista_peso_converttoDouble = result[2];
    novaLista.peso = Convert.ToDouble(lista_peso_converttoDouble);
    string lista_items_converttoInt = result[3];
    novaLista.itens = Convert.ToInt32(lista_items_converttoInt);

    primContext.ListasPickingGet.Add(novaLista);
    primContext.SaveChanges();

    return StatusCode(HttpStatusCode.Created);
}

I trying some solutions related to this kind of problem, and the same error (s).

Web.config

UPDATE

When I rebuild my solution, i'm getting some lines like this:

Files\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\Microsoft.Common.CurrentVersion.targets(1964,5): warning MSB3270: There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "Interop.ICrmDS800", "x86". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project

Can be the problem? Interop.dll is a file that i include in my project to use a external program to get the information about sales order.

SOLUTION

The [Key] annotation is missing in "ListaPicking" Model, and i was passing a DateTime variable with default value... I just change to for example DateTime.Today and now it's working :)

You could just send the entire model

public async Task AddTarefa(ListasPicking listaPickingAdd) {

    var response = await cliente.PutAsJsonAsync("api/ListasPicking/", listaPickingAdd);

    return response.IsSuccessStatusCode;        
}

And receive it at the action the same way instead of deconstructing and reconstructing it.

[ResponseType(typeof (ListasPicking))]
[HttpPut]
public  IHttpActionResult PutLista ([FromBody] ListasPicking novaLista) {
    if(!ModelState.IsValid) {
        return BadRequest(ModelState);
    }

    primContext.ListasPickingGet.Add(novaLista);
    primContext.SaveChanges();

    return StatusCode(HttpStatusCode.Created);
}
