I'm trying to read this Json that contains fixes, but it gives me the following error, I'm reading it with JSONArray, I tried to traverse it with a for but it does not let me extract the objects inside the json. Does anyone know what I can do or what am I doing wrong?

how to create a global variable and store values in an ajax request [duplicated] My Yii2 application does not work well when I upload it to the server

What happens is that your response is not a JSONArray, what you are receiving is a JSONObject, therefore the error when initializing the JSONArray, if what you expect is a JSONArray as such, I recommend changing the structure of your answer in JSON, meanwhile here I leave you a solution to your problem so that from your answer you can get a JSONArray, this code is already tested with the response that you put in this publication

String response = ""; //TU RESPONSE
    try {
        JSONObject jsonObject = new JSONObject(response);
        Iterator<String> iterator = jsonObject.keys();
        JSONArray jsonArray = new JSONArray();
        while (iterator.hasNext()) {
            String key = iterator.next();
            JSONObject object = new JSONObject(jsonObject.get(key).toString());
            jsonArray.put(object);
        }
        Log.d("TAG", jsonArray.toString());
    } catch (JSONException e) {
        e.printStackTrace();
    }

If you have any errors, or any questions, do not hesitate to answer, greetings.

This is an example of how you can navigate your parent array and the array of promos of each item in your parent array.

        //Iterar JSONArray
        for (int i = 0; i < jsonArray.length(); i ++){
            JSONObject item = jsonArray.getJSONObject(i);
            String nombre = item.getString("nombre");
            JSONArray jsonArrayPromos = item.getJSONArray("promos");
            //Iterar JSONArrayPromos
            for (int j = 0; j < jsonArrayPromos.length(); j ++) {
                JSONObject itemPromo = jsonArrayPromos.getJSONObject(j);
                //Ejemplo de como extrar cada propiedad
                String prom_id = itemPromo.getString("prom_id");
                String neg_id = itemPromo.getString("neg_id");
               //...
                Log.d("TAG",  i + " " + itemPromo.toString());
            }
        }
