[Python] vk-bot - get the file from attachments

I need help with a VK bot. It should take text from a file sent by the user, then receive an image, and finally send a post with the text and image to the group it is connected to. I can't get the file from attachments.

elif current_state[user_id] == 'text' and hasattr(event, 'attachments'):
for attach in event.attachments:
if attach[-5:] == '_type':
continue
tp = event.attachments[attach + '_type']
doc = vk.docs.getById(docs=event.attachments
