Why does it give an error 100 when sending a photo to VK api?

Question

API

I send a photo to the VK bot, it accepts them, when I ask them to send - sends, but when my friends send, the bot also accepts them, but when I try to send - the photos do not come. I tried to send a photo through the search bar, entered it in attachment=photo (friends photo data), I got an error 100. And with my photo data everything is sent, what's the problem?

Answer 1

the problem with the rights
you need to download and then upload the photo when sending and everything will be ok
the bugfix is ​​in vkakmene most likely,
