Crooked Odnoklassniki API?

Question

Classmates

Good day, I ran into a problem with a strange response from the Odnoklassniki API, when I requested a discussion, it gave me the following json
{
"discussion": {
"title": "Imagine that one fine day you suddenly have a sister and father, about which you , neither she knew anything before. In addition, along with your newfound relatives, you have to pull off a scam for 15 million. In such a situation, something will definitely go awry! \nWatch the comedy "The Family Heist" in our Video Store!",

what's the point, when creating a link
using this json, you get this link https://ok.ru/discussions/3/53279181701233/6711997...
it's not working, so attrs=p=3 and should be equal to 1
Question to the developers of classmates, how is this possible?
