TypeError: answer() got an unexpected keyword argument reply_markup

Question

我的代码是：

@dp.callback_query_handler(text='add word')
async def add_word(message: Message):

    keyboard = all_dictionaries_keyboard()
    await message.answer('Please choose dictionary at which words will be added:',
                         reply_markup=keyboard)
    await AddWords.get_dictionary.set()

为什么 answer() 在这里说出意想不到的论点，但在其他地方都有效？

我认为这不会提供更多信息，但这里有完整的回溯：

Answer 1

所以解决方案是改用回复键盘。

尽管电报机器人总是会收到来自用户的消息（用户需要发送 /start 命令才能使用机器人），但如果您使用内联键盘作为用户的第一个操作，然后尝试读取回调，您将收到此错误是因为 aiogram 看不到来自用户的消息。在我的案例中，甚至是用户发送的命令/菜单。
