How to get an access key for attachments in VK?

Question

Python

I have a message with an attachment -- a photo. VK api allows you to get its ID in the userid_photoid format. Question: How can I get an access key for this photo? method

api.photos.getById(photos=str(event.attachments['attach1']))

throws a 200, access denied error.

update: noticed that the 200 error always occurs when I copy and paste an image into a dialog. When I take it from the saved photos, the error does not appear.

What's in event.attachments['attach1'] if you print the value?
