discord.py: AttributeError: 'NoneType' object 沒有屬性 '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

我不知道為什么會出現這個錯誤，因為它沒有任何意義。 我試圖更改disnake.utils.get function，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)

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

它明確指出： If nothing matching the passed attributes is found, None is returned.

當在可迭代序列disnake.utils.get中獲取值沒有結果時，將值 None 放入user變量中
