Discord 模式回调从未被调用。模态窗口给出“出了问题”错误，但控制台中没有错误

Question

通过命令生成模型：

@discord.app_commands.command(name="host_game_test", description="Host a new game")
async def host_game_test(self, interaction: discord.Interaction):
    modal = HostGameModal(title="Host New Game", era=GameAge.EA)
    await interaction.response.send_modal(modal)

这工作得很好，创建了模式窗口。然而，填写完毕并单击“提交”后，一段延迟后出现红色错误消息 - “出现问题。请重试。”控制台中根本没有报告任何错误。

从不和谐导入交互，文本样式 从discord.ui导入TextInput，Modal

from utils import printlog

HostGameModal 类（模态）： def init(self,era:str,*args,**kwargs): super().init(*args, **kwargs) self.era =era # 存储时代

    self.add_item(TextInput(label="Game Name", custom_id="game_name", placeholder="Enter your game's name"))
    self.add_item(TextInput(label="Max Players", custom_id="max_players", placeholder="Enter max number of players",
                            style=TextStyle.short))
    self.add_item(TextInput(label="Password", custom_id="password", placeholder="Enter a game password",
                            style=TextStyle.short))

async def callback(self, interaction: Interaction):
    printlog("HostGameModal callback called.")
    try:
        await interaction.response.defer(ephemeral=True)

        game_name = self.children[0].value
        max_players = int(self.children[1].value)
        password = self.children[2].value
        # Use self.era here for the game's era
        await interaction.followup.send(f"Hosting a '{self.era}' game named '{game_name}' with max {max_players} "
                                        f"players and password '{password}'.")
    except Exception as e:
        printlog(f"Error in HostGameModal callback: {e}")
        await interaction.followup.send("An error occurred. Please try again later.", ephemeral=True)

这是 Modal 类。回调函数开始处的 printlog 从未被调用，因此似乎由于某种原因回调函数从未被调用。

已经被这个问题困扰了一段时间，而且我能找到的关于模态内容的文档似乎并不多。谁能看出问题出在哪里吗？

Modals 使用 on_submit 方法作为回调。创建方法

callback

不会被调用，因为模式正在寻找 on_submit 方法。

class MyModal(discord.ui.Modal):
    def __init__(self):
        super().__init__()

    async def on_submit(self, interaction: discord.Interaction):
        #  Do stuff
