I can’t understand why I can’t connect a test payment from Sberbank in a telegram chat bot?

Question

Bots

Hello!
I tried to connect Yukassu, Tranzzo and PayMaster to my telegram bot in test mode, and everything worked. But when I began to try SberBank, it began to give out such an error.

Googling didn't work. I did not find any information from the Savings Bank or from the telegram. The Sberbank chatbot only sent me a link to the data with test cards from the documentation.
I did this article. It seems that the data being sent is the same as in the article from Habr . Can you please tell me what could be the problem and how to solve it?
