Attachments are empty when running thread and reading messages

I am using Python API to request Open AI for the file modifications. Every time I make a request assistant replies with a link to download an attachment, however attachment list is always empty. It was working a couple of times, but not anymore.

Assistant creation:

    new_assistant = ai_client.beta.assistants.create(
        model=CARBON_MODEL,
        instructions=CARBON_INSTRUCTIONS,
        name=CARBON_PROJECT,
        tools=[
            {
                "type": "code_interpreter",
            }
        ]
    )

Running thread:

def run_thread(thread_id):
    assistant_id = get_assistant()

    run = ai_client.beta.threads.runs.create_and_poll(
        assistant_id=assistant_id,
        thread_id=thread_id,
    )

    if run.status == "completed":
        process_thread(thread_id, run.id)

Processing thread:

def process_thread(thread_id, run_id = None):
    if run_id is None:
        messages = ai_client.beta.threads.messages.list(
            thread_id=thread_id
        )
    else:
        messages = ai_client.beta.threads.messages.list(
            thread_id=thread_id,
            run_id=run_id
        )

    for message in messages:
        if message.role == "assistant":
            for block in message.content:
                if block.type == "text":
                    parsed_json = extract_json_from_text(block.text.value)

                    #if "file_id" in parsed_json:
                    #    save_file(parsed_json["file_id"])

        for attachment in message.attachments:
            save_file(attachment.file_id)

If I uncomment lines to get file_id from JSON output, I then get a following error:

Could not save file: Error code: 400 - {'error': {'message': 'Not allowed to download files of purpose: assistants', 'type': 'invalid_request_error', 'param': None, 'code': None}}

It looks like I can either ask an output in JSON format or FILE output. It cant’t output both.

When JSON is outputted, attachments are not present. If I don’t request for JSON output I can see and download attachments.
