discord.py: AttributeError：'NoneType‘对象没有属性'name’

Question

Traceback (most recent call last):
  File "C:\Users\Elyes\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\site-packages\disnake\ui\modal.py", line 229, in _scheduled_task
    await self.callback(interaction)
  File "d:\Workspaces\Python Workspaces\Discord Bots\JustMe Bot\bot.py", line 143, in callback
    print(user.name)
AttributeError: 'NoneType' object has no attribute 'name

我不知道为什么这个错误显示，因为它没有任何意义。我试图更改disnake.utils.get函数，但它不起作用。

# The callback received when the user input is completed.
    async def callback(self, inter: disnake.ModalInteraction):
        # Get the input from the modal
        for key, value in inter.text_values.items():
            # get user by name
            if key == "name":
                # split value by #
                username, discriminator = value.split("#")
                user = disnake.utils.get(inter.channel.guild.members, name=username, discriminator=discriminator)
                print(user.name)

参考文档https://docs.disnake.dev/en/latest/api.html?highlight=utils#disnake.utils.get

它清楚地指出：If nothing matching the passed attributes is found, None is returned.

当没有在可迭代序列中获得值的结果时，disnake.utils.get将值None放在user变量中
