@rbiseck3 我猜你能指出为什么会出现这个问题。我认为 download_dir 的问题出在这里：https://github.com/Unstructured-IO/unstructured/blob/main/unstructured/ingest/interfaces.py#L164
我认为这里应该使用 download_dir: Optional[str] = None 而不是 download_dir: str = ""。你觉得对吗？
additional_partition_args 的定义在这里，我相信它也应该被定义为 Optional[Dict[str, str]]。
https://github.com/Unstructured-IO/unstructured/blob/main/unstructured/ingest/interfaces.py#L79
你能为我们确认一下吗？
