I don't know how to use an attribute of a JSON

I was looking for access an JSON attribute in JavaScript, that come from an aspnet (so for that is the dotnet tag).

The connection with js and aspnet is this:

function PostAsociado()
{
    const sePuedeCargar = AsociadoCanPost(); 
    const AsociadoObject = SetAsociadoObject();
    var htmlState = document.getElementById('StateExecution');

    const response = fetch(urlAsociado,
        {
            method : 'POST',
            headers: 
            {
            'accept' : 'application/json',
            'Content-Type' : 'application/json',    
            },
            body : JSON.stringify(AsociadoObject) 
        })
        .then(response => response.json())

        alert(response.executionSuccessful);

    if(response.executionSuccessful)
    {
        htmlState.innerHTML = "El asociado " +asociado.Nombre + " "+ asociado.Apellido  +" se ha cargado exitosamente.";
        htmlState.style.color = "green"; htmlState.style.display = "inherit"; 
    }
    else
    {
        htmlState.innerHTML = "El dni ya fue ingresado.";
        htmlState.style.color = "red"; htmlState.style.display = "inherit";
    }
}

This is the response class, the language used is C#, (each class have their own file, I just display in that way because is more easy to understand):

    public abstract class Response
    {
        public bool ExecutionSuccessful {get; set;}
        public string? ErrorMessage {get;set;}
    }

  public class AsociadoPostResponse: Response
    {
        public Asociado? asociado {get; set;}
    }
