How to properly generate json mediatopic.post with attachment "type": "photo" (bad photo id problem)?

Question

Classmates

Following the mediatopic.post instructions, I upload a photo and attach it as an attachment in the json of the form:

{"media":[{"type":"photo","list":[{"id":"===здесь токен загруженного изображения==="},{"photoId":"==здесь id загруженного изображения=="}]}]}

In this case, the photoId variable fully corresponds to the one obtained earlier at the step of obtaining this very ID and download address. I get a "bad photo id"
error . Are there any errors in the manual? What could be the problem?

Answer 1

Found the answer myself.
On the same page of the description of the mediatopic.post method, it is written that it is impossible to specify an album when publishing to a group wall and that only one of the parameters in the list must be specified : either id or photoId .
If only instead of the "bad photo id" error, people like me would get the error "Only one of two parameters should be specified".
Removed aid, photoId and everything worked!
