Pyrogram: telegram API在search_messages()请求后返回400: INPUT_FILTER_INVALID

Question

我正在尝试收集聊天中语音笔记的统计信息，比如数量和平均长度；我之前用telethon实现过这个功能：

await client.get_messages(entity=chat, from_user=my_id, filter=telethon.types.InputMessagesFilterVoice)

但现在我决定换成pyrogram，重写了一些基本逻辑，并使用了请求：

async for vc in __usr__.search_messages(message.chat.id, filter=pyrogram.enums.MessagesFilter.VOICE_NOTE, from_user=message.chat.id): ...

结果我遇到了以下错误：

(2024-03-29 20:05:30,835) [ERROR] Telegram says: [400 INPUT_FILTER_INVALID] - The filter is invalid for this query (caused by "messages.Search")

    r = await self.session.invoke(

    return await self.send(query, timeout=timeout)

    raise getattr(
pyrogram.errors.exceptions.bad_request_400.InputFilterInvalid: Telegram says: [400 INPUT_FILTER_INVALID] - The filter is invalid for this query (caused by "messages.Search")

这是我代码的一部分：

async def __voice_info__(message: pyrogram.types.Message):
    if not message.chat or not message.from_user:
        return

    ...

    async for vc in __usr__.search_messages(message.chat.id,
                                            filter=pyrogram.enums.MessagesFilter.VOICE_NOTE,
                                            from_user=message.chat.id):
        ...

    ...

    async for vc in __usr__.search_messages(message.chat.id,
                                            filter=pyrogram.enums.MessagesFilter.VOICE_NOTE,
                                            from_user=message.from_user.id):
        ...

    answer = "..."
    await message.reply(answer)

我在网上搜索了很久，没找到为什么voice_note是无效过滤器的原因。__usr__确实是用户，而不是机器人。
