Hello, I am trying to download an invoice in PDF format in a local folder to be able to modify it but I have not found any solution. I use the XML-RPC client to download but I couldn't, I attach the code. Can anyone help me?

Thanks

from flask import Flask, request, jsonify, send_file

import xmlrpc.client

import requests

import base64

url = 'url'

db = 'db'

username = 'username'

password = 'password'

session_url = f'{url}web/session/authenticate'

data = {

    'jsonrpc': '2.0',

    'method': 'call',

    'params': {

        "service": "common",

        "method": "login",

        'db': db,

        'login': username,

        'password': password,

    }

}

session_response = requests.post(session_url, json=data)

session_data = session_response.json()

session_id = session_response.cookies['session_id']

common = xmlrpc.client.ServerProxy('{}/xmlrpc/2/common'.format(url))

uid = common.authenticate(db, username, password, {})

models = xmlrpc.client.ServerProxy('{}/xmlrpc/2/object'.format(url))

invoice_id = 1

invoice = models.execute_kw(db, uid, password, 'account.move', 'read', [invoice_id], {'fields': ['name']})

print("Invoice details:", invoice)

report_action = models.execute_kw(db, uid, password, 'ir.actions.report', 'search_read', [[['model', '=', 'account.move'], ['report_type', '=', 'qweb-pdf']]], {'fields': ['id', 'name']})

print("Available reports:", report_action)

if report_action:

    report_id = report_action[0]['id']

    report_data = models.execute_kw(db, uid, password, 'account.move', 'action_invoice_print',  [invoice_id])

    pdf_content = base64.b64decode(report_data[0])

    filename = '{}.pdf'.format(invoice[0]['name'])

    with open(filename, 'wb') as f:

        f.write(pdf_content)

    print(f"PDF saved as {filename}")

else:

    print("No suitable report found for invoices.")
