我正在开发 Django 项目，我的测试用例遇到了一些问题。具体来说，我在与用户配置文件更新和用户创建相关的两个测试用例方面遇到问题。
有人可以帮助我确定可能导致这些测试失败的原因以及如何修复它们吗？任何见解或指导将不胜感激。
这是我收到的错误消息：
======================================================================
FAIL: test_update_user_profile (user.tests.test_user_api.PrivateUserApiTests)

预先感谢您的协助！
我怀疑这两个错误是相关的。当您应该传递 JSON 字符串时，您正在传递一个 python 对象，例如，
res = self.client.post(CREATE_USER_URL, payload, content_type='application/json')
您需要将
payloadimport json
...
payload_json = json.dumps(payload)
res = self.client.post(CREATE_USER_URL, payload_json, content_type='application/json')
