Why is empty file uploaded to python vk_api conversation?

Question

Python

I'm trying to upload a local file to a conversation. I tried both through the built-in vk_api methods , and the method from the documentation. Here is the code for the latter:

method = vk.docs.getMessagesUploadServer(peer_id=event.message.peer_id)["upload_url"]
file = requests.post(method, files={'file': open(f'data/{filename}', "rb")})
if file.status_code == 200:
    file = file.json()['file']
    uploaded = vk.docs.save(file=file)
    vk.messages.send(
        key=(bot_config['key']),
        server=(bot_config['server']),
        ts=(bot_config['ts']),
        random_id=get_random_id(),
        message=f' {first_name} {last_name}\n\n{text}',
        chat_id=event.chat_id,
        attachment=f"doc{uploaded['doc']['owner_id']}_{uploaded['doc']['id']}")
else:
    answer(' Не получилось загрузить файл. Попробуйте обновить данные.', event.chat_id)

The bot doesn't throw any errors, docs.save returns file data and a link, but the file itself is empty. It is attached, the size in the message is correct, but there is no pikchi itself.




I'm using vk_api 11.9.4 (latest); Longpoll 5.131 (latest)

Answer 1

It helped me to replace the method with docs.getWallUploadServer and the file was uploaded to the group files, but at the same time it became possible to download it in the conversation (I have Node js)

Answer 2

The code is working. Maybe the file is broken? Does the document open on other devices? From the phone, let
’s either try to download the file and see what loads
