我很累发送一些文件到电报，但程序收到错误404.
这是我的代码：

import json
import requests

chat_id ="-"
TOKEN = "--"

data = {
    "chat_id": chat_id,
    "document": json.dumps([
        {"type": "document", "document":"attach:path_to_file"},
        {"type": "document", "document":"attach:path_to_file"}
# paths are like C:\\a\\b\\c\\d.jpg
    ])
}

files = {
    "photo1.png" : open("path_to_file", 'rb'),
    "photo2.png" : open("path_to_file", 'rb')
}

temp = requests.post("https://api.telegram.org/bot" + TOKEN + "/sendDocumentGroup", data=data, files=files)

print(temp.json())

错误显示如下：

{'ok': False, 'error_code': 404, 'description': 'Not Found'}
