Find Object Retrieval

yes, It's the same code as above, it's a simple query, it's intermittent again because sometimes it brings it to me and sometimes it doesn't.

type or paste code here
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using BackendlessAPI;
using System;
using BackendlessAPI.Data;
using BackendlessAPI.Async;
using BackendlessAPI.Persistence;
using Newtonsoft.Json;
using System.Linq;
using UnityEngine.SceneManagement;
using BackendlessAPI.Exception;

public class Pruebas : MonoBehaviour
     void Start()


        DataQueryBuilder queryBuilder = DataQueryBuilder.Create();
        queryBuilder.SetWhereClause("users_related in ('" + "4705FC99-9077-4477-8243-CCE6E7471EAE" + "')");

        AsyncCallback<IList<Dictionary<string, object>>> findCallback;
        findCallback = new AsyncCallback<IList<Dictionary<string, object>>>(
          foundObjects =>
          error =>
              print("Server returned an error " + error.Message);

        Backendless.Data.Of("quiz_groups").Find(queryBuilder, findCallback);


Could you please check if it is working now?

If everything works fine so far, can I know what it was?

Let’s confirm that it works first.

Sorry for the delay in answering, I checked everything these days and so far it works fine
