android - 方法引发了“java.lang.StackOverflowError”异常。无法评估 org.json.JSONObject.toString() - 在调用 json post 方法时

Question

调用 api 的代码如前所述和 json 响应发布方法。在“JSONObject mJsonObj = new JSONObject(response);”行调用 json 对象时出错。响应可用，但发生错误为“方法抛出 'java.lang.StackOverflowError' 异常。无法评估 org.json.JSONObject.toString()”

String PROJECT_URL = url+ r.getString(R.string.api_Get_two);
        mProgressBar.setVisibility(View.VISIBLE);
        StringRequest stringRequest = new StringRequest(Request.Method.POST, PROJECT_URL,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        pendingDataList.clear();
                        Log.d("JSON", response);
                        try {
                            JSONObject mJsonObj = new JSONObject(response);  (Error here)
                            JSONArray pendingChallans = (mJsonObj).getJSONArray("Day");
                            if(pendingChallans.length() > 0) {
                                for (int i = 0; i <pendingChallans.length() ; i++) {
                                PendingData pending = new PendingData();
                                 JSONObject obj = (JSONObject) pendingChallans.get(i);
                                  pending.setRowType(obj.getString("RowType"));
                                  pendingDataList.add(pending);
                                }
                            }else {
                                new Dialogs(mContext, "No Data Found .").createDialogWithMsg();
                            }
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }finally {
                            mProgressBar.setVisibility(View.GONE);
                            pcdRecyclerview.setVisibility(View.VISIBLE);
                            myAdapter.notifyDataSetChanged();
                        }
                    }
