Why does the telegram bot spam after pressing the inline button?

Question

Telegram

I write in Python using python-telegram-bot
Essence:
When you press the inline button, a simple message should be sent in response.
What happens:
When you press the inline button, a message is sent, but if you lock the screen on your phone (close the telegram client), the bot will duplicate the message. If after that you open the telegram client and enter the chat with the bot, then the bot will slap a couple more duplicates of the previous message. Of course, that this nonsense should not be.
Inline button click handler code:

def button(self, bot, update):
        query = update.callback_query
        if query.data == 'getOrderInfoByID':
              bot.send_message(parse_mode='HTML', chat_id=query.message.chat_id, text='Текст')

The code is terribly simple.
I can't figure out why this is happening.

Answer 1

The problem is not knowing the Telegram API)
When using the Inline Callback Query, Telegram will spam updates until it receives a response to the callback (not some kind of action like sending a message, but specifically the response to the callback!)
