属性错误：“NoneType”对象没有属性“message_id”

Question

我已经在Python-Telegram-bot包装器中创建了回调函数。

def add2(update: Updater, context: CallbackContext):
    query = update.callback_query  
    # add()
    query2 = link1
    _mirror(bot, update, query2)
    query.answer()

但是我会得到属性：'nontype'objcet没有属性'message_id'

是_mirror函数的链接：

_mirror 函数将 update 传递给 MirrorListener，它显然假设 update.message 不是 None< /代码>。但 add2 回调显然用作 CallbackQueryHandler 的回调，因为您访问 update.callback_query。
