How to use CallbackQuery properly?

[HitaloM]

I am using the InlineKeyboardBuilder to create buttons and CallbackData to set data. I am using CallbackQuery to filter this data with callback.filter(). However, when I click on the buttons, nothing happens - not even in the logs - and no error appears. It seems as if nothing is really happening.

I have attempted all possible methods that I am aware of by following the documentation, but I have not been able to achieve the desired outcome. As a newcomer to aiogram, it is possible that I have made a trivial error. However, after spending several hours reviewing the documentation and searching for solutions on GitHub and Telegram groups, I have decided to seek assistance.

router = Router(name="callback")

class MyCallback(CallbackData, prefix="testcbdata"):
    test: str


@router.message(Command("test"))
async def language(message: Message):
    keyboard = InlineKeyboardBuilder()
    keyboard.button(text="Test", callback_data=MyCallback(test="f"))
    keyboard.adjust(4)
    await message.reply("Just a test", reply_markup=keyboard.as_markup())


@router.callback_query(MyCallback.filter())
async def language_callback(callback: CallbackQuery):
    await callback.answer("Hi", show_alert=True)

I found out what was causing the CallbackQuery to be ignored, was that I set bot.delete_webhook(drop_pending_updates=True) for the bot to ignore updates from when it was off, this is probably not the right way to do it.

In aiogram==3.0.0b7 do not forget to alter callback_data=MyCallback(test="f") to callback_data=MyCallback(test="f").pack(), it's necessary to add .pack()

if you're using the builder, you don't have to
