I want to test my new assistant but I get an error when I execute the run method

the error is Bad request or error 400

{StatusCode: 400, ReasonPhrase: 'Bad Request', Version: 1.1, Content: System.Net.Http.HttpConnectionResponseContent, Headers:

I was thinking my old apiKey was the problem but I have created a new one and the problem continues

I have checked the url and it is correct:
URL is https://api.openai.com/v1/threads/threadId/runs
this is my code:

public async Task<string> RunAssistantAsync(string assistantId, string threadId)
        {

            _httpClient = new HttpClient();


            _httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            _httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", _apiKey);
            _httpClient.DefaultRequestHeaders.Add("OpenAI-Beta", "assistants=v2");  // Este es el encabezado necesario para assistants

            var url = $"{_apiUrl}/threads/{threadId}/runs";

            var requestBody = new
            {
                assistant_id = assistantId
            };

            var jsonContent = new StringContent(JsonConvert.SerializeObject(requestBody), Encoding.UTF8, "application/json");

            var response = await _httpClient.PostAsync(url, jsonContent);

            if (!response.IsSuccessStatusCode)
            {
                throw new Exception($"Error al ejecutar Run: {response.StatusCode}, {response.ReasonPhrase}");
            }
            else
            {

                var responseContent = await response.Content.ReadAsStringAsync();
                dynamic jsonResponse = JsonConvert.DeserializeObject(responseContent);
                return jsonResponse.id;
            }

        }

how can solve this problem?

thanks in advance

I just set requestBody and the magic was done

var requestBody = new
            {
                assistant_id = assistantId,
                instructions = "Por favor, responde.",
                response_format = new {
                    type = "text"
                }
            };

Sauldos amigos…
