Python 如何修复discord.py中cogs中的asyncio.sleep错误

因此，基本上这是一个cog文件夹，其中mute命令在特定时间向成员添加mute角色。我制作了一个函数

converts

，它将时间转换为秒，因为

asyncio.sleep（）

需要秒。但是我得到了一个错误：-

TypeError:“错误显示在哪一行？在
await asyncio.sleep（time）
line中，您可以共享整个回溯吗？
class Mod(commands.Cog):
    def __init__(self,client:commands.Bot):
        self.client = client
    def converts(time):
        pos = ["s","m","h","d","y"]

        time_dict = {"s" : 1, "m" : 60, "h" : 3600 , "d" : 3600*24, "y" : 86400*365}

        unit = time[-1]

        if unit not in pos:
            return -1
        try:
            val = int(time[:-1])
        except:
            return -2
        return val * time_dict[unit]
