python - Discord NoneType 对象 Discord 文件中出现错误？

Question

我已经和不和谐机器人混在一起有一段时间了，今天我遇到了这个错误。我想看看是否有人可以帮我解决这个问题。

错误以及我正在运行的事件将发布在底部。

我正在为我的不和谐服务器制作一个票证系统，我发现如果不使用 On_Raw_Reaction_Add 事件，我就无法做到这一点。有效负载似乎让我感到非常困惑，但我几乎一切都可以工作。最后剩下的就是公会了。由于某种原因，当使用下面的片段引用/拉动公会时，在 guild.py 中关于不和谐导入的情况下，它说公会被认为是 NoneType 但如果我从事件中打印它，它工作得很好。我只是想创建一个 channel 。

guild = self.client.get_guild(reactionpayload.guild_id)

    async def on_raw_reaction_add(self, reactionpayload):
        print('ran')
        db = sqlite3.connect(DATA_FILENAME)
        cursor = db.cursor()
        cursor.execute(f"SELECT ID FROM Ticket_Channel")
        channelID = cursor.fetchone()[0]
        cursor.close()
        channel = self.client.get_channel(int(channelID))
        if channel is None:
            print('Ticket System: Channel not Found!')

get_member 采用 id，而不是 User 对象，因此 guild.get_member(self.client.get_user(reactionpayload.user_id))返回None。

@commands.Cog.listener()
async def on_raw_reaction_add(self, reactionpayload):
    if not reactionpayload.guild_id:
        return  # Private message
    print('ran')
    db = sqlite3.connect(DATA_FILENAME)
    cursor = db.cursor()
    cursor.execute(f"SELECT ID FROM Ticket_Channel")
    channelID = cursor.fetchone()[0]
    cursor.close()
    channel = self.client.get_channel(int(channelID))
    if channel is None:
        print('Ticket System: Channel not Found!')
    else:
        if reactionpayload.message_id == channel.last_message_id:
            if not self.client.get_user(reactionpayload.user_id).bot:
                guild = self.client.get_guild(reactionpayload.guild_id)
                member = guild.get_member(reactionpayload.user_id)
                print(guild.id)
                name = 'ticket-' + member.name
                overwrites = {
                    guild.default_role: discord.PermissionOverwrite(read_messages=False),
                    guild.me: discord.PermissionOverwrite(read_messages=True),
                    member: discord.PermissionOverwrite(read_messages=True)
                }
                channel = await guild.create_text_channel(name, overwrites=overwrites, category=channel.category, position=100)
                await remove_reaction('\U0001F4E9', self.client.get_user(reactionpayload.user_id))
        else:
            print(reactionpayload.message_id)
            print(channel.last_message_id)
