Discord.ext.commands.errors.CommandInvokeError：命令引发异常：KeyError：'594750729810477063'。就是这么说的。我不是这方面的专家，所以，任何帮助将不胜感激！

完整回溯如下：

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

您的open_account函数看起来不会执行您需要执行的操作。如果还没有给定用户的新帐户，您需要它来创建一个新帐户。但是您没有任何代码来检查现有用户（看起来您正在尝试，但有一个拼写错误），并且您也没有代码来创建内部字典。这就是我认为你想要的：async def open_account(user):    users = await get_bank_data()    if str(user.id) in users:                         # note, use "in" here rather than "is"        return False    users[str(user.id)] = {"Simp Wallet": 0, "Simp Bank": 0}  # create inner dictionary here    with open('mainbank.json',"w") as f:        json.dump(users,f)    return True
