I'm working on a Django project, and I'm encountering some issues with my test cases. Specifically, I'm having problems with two test cases related to user profile updates and user creation.

我正在做一个Django项目，我的测试用例遇到了一些问题。具体地说，我在两个与用户配置文件更新和用户创建相关的测试用例中遇到了问题。

Could someone please help me identify what might be causing these test failures and how to fix them? Any insights or guidance would be greatly appreciated.

有人能帮我找出可能导致这些测试失败的原因以及如何修复它们吗？如有任何见解或指导，我们将不胜感激。

Here's the error message I'm getting:

以下是我收到的错误消息：
