Incorrect Yandex Documents link format
ERR.FILE.INVALID_LINK.YADOCS_INVALID_PUBLIC_LINK_PREFIX
The error occurs when creating a connection to Yandex Documents if the link to the file you are adding contains /d instead of /i. For example:
https://disk.yandex.ru/i/idis the correct URL format.https://disk.yandex.ru/d/idis the incorrect URL format.
To fix the problem, delete the URL to your Yandex Documents file and after a while generate a new one.
