AsyncClient.download() always M_NOT_FOUND?

[Rouji]

Hello!

I think this is probably a brainfart, but I just can't figure out where I'm going wrong.

I took one of the examples and tried making it download all RoomMessageFile that cross its path

        async with aiofiles.open(CONFIG_FILE) as f:
            contents = await f.read()
        config = json.loads(contents)
        client = AsyncClient(config["homeserver"])

        client.access_token = config["access_token"]
        client.user_id = config["user_id"]
        client.device_id = config["device_id"]

        async def message_callback(room: MatrixRoom, event: RoomMessageFile) -> None:
            try:
                print(room.name, event.source['content']['body'], event.url)
            except:
                pass
            try:
                dl = await client.download(mxc=event.url, save_to=event.source['content']['body'], allow_remote=True)
                if isinstance(dl, DownloadError):
                    print(dl)
            except Exception as e:
                print(e)


        client.add_event_callback(message_callback, RoomMessageFile)

        await client.sync_forever(timeout=30000)  # milliseconds

whole file

...but I always get M_NOT_FOUND. Element and other clients can download the same files, using the same mxc:// address just fine.

Any ideas?
