NextCord：使用转换器在Slash命令中使用转换器的错误

Question

我有discord.py和pycord的背景，我决定尝试NextCord Slash命令 因此，我决定创建一些命令，在此中，我收到了一个特殊的错误消息

@slash_command(name='suggestions_set', guild_ids=[956174862815199252])
async def suggestions_set(self, interaction: Interaction, channel: TextChannel):
   db.insert({'channel': channel.id})
   await interaction.send(f'**The suggestions channel has been set to {channel.mention}**')

，我收到以下错误：

Traceback (most recent call last):
  File "C:\Users\angel\anaconda3\envs\spybot\lib\site-packages\nextcord\ext\commands\bot.py", line 675, in _load_from_module_spec

    app_cmd = ApplicationCommand(
  File "C:\Users\angel\anaconda3\envs\spybot\lib\site-packages\nextcord\application_command.py", line 1418, in __init__
    super().__init__(

    self._from_callback(callback)
  File "C:\Users\angel\anaconda3\envs\spybot\lib\site-packages\nextcord\application_command.py", line 820, in _from_callback
    arg = CommandOption(param, self)
  File "C:\Users\angel\anaconda3\envs\spybot\lib\site-packages\nextcord\application_command.py", line 327, in __init__
    self.type: ApplicationCommandOptionType = self.get_type(parameter.annotation)
  File "C:\Users\angel\anaconda3\envs\spybot\lib\site-packages\nextcord\application_command.py", line 384, in get_type
    raise NotImplementedError(
NotImplementedError: Type "<class 'nextcord.application_command.SlashOption'>" isn't a supported typing for Application Commands.

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\angel\Code\Python\spybot\bot.py", line 19, in <module>
    bot.load_extension(f'cogs.{file[:-3]}')
  File "C:\Users\angel\anaconda3\envs\spybot\lib\site-packages\nextcord\ext\commands\bot.py", line 789, in load_extension
    self._load_from_module_spec(spec, name, extras=extras)
  File "C:\Users\angel\anaconda3\envs\spybot\lib\site-packages\nextcord\ext\commands\bot.py", line 678, in _load_from_module_spec
    raise errors.ExtensionFailed(key, e) from e
nextcord.ext.commands.errors.ExtensionFailed: Extension 'cogs.info' raised an error: NotImplementedError: Type "<class 'nextcord.application_command.SlashOption'>" isn't a supported typing for Application Commands.

我知道这一定是某种类型的实现错误，但我不明白，如果有人能告诉我我在做什么错？

频道：textChannel = slashoption（...）应根据其 github存储库。
