使用PYTHON程式抓取研究報告/ How to use Pthon to fetch Research report

想透過Python程式抓取研究報告，
如以APPL為例子，抓取最新3則研究報告
底下是我的sample code
但目前都抓不到資料 (No results found.)
不知道是哪邊出了問題?

I want to fetch research reports using a Python program.
For example, using AAPL as a case, I want to fetch the latest 3 research reports.
Below is my sample code, but currently, I can't fetch any data (shows No results found.).

I don't know where the problem is.

import refinitiv.dataplatform as rdp

import json

import os


API_KEY = 'xxxxxxxx'


rdp.open_desktop_session(API_KEY)


symbol = 'AAPL.O'


def get_latest_reports(symbol, count=3):

    try:

        query = {

            "query": {

                "view": "research",

                "filter": {

                    "symbol": symbol,

                    "language": "en",

                    "limit": count

                }

            }

        }


        response = rdp.search(query)


        print("Query:", json.dumps(query, indent=2))

        print("Response:", response)


        if response is None or 'results' not in response:

            print("No results found.")

            return


        reports = response['results']


        for report in reports:

            report_id = report['reportId']

            pdf_url = report['pdfUrl']

            pdf_response = rdp.get(pdf_url)


            if pdf_response is None:

                print(f"Failed to download report {report_id}")

                continue


            pdf_filename = f"{symbol}_{report_id}.pdf"

            with open(pdf_filename, 'wb') as pdf_file:

                pdf_file.write(pdf_response.content)


            print(f"Downloaded {pdf_filename}")


    except Exception as e:

        print(f"Error: {e}")


get_latest_reports(symbol, count=3)


rdp.close_session()

Thanks.
