redux React/Django用户注册给了我(400 Bad Request)

当我尝试通过前端注册新用户时，它不会自动登录我，它告诉我这些新用户的电子邮件已经存在。从我在Django Admin中看到的，用户确实被保存/注册了，我可以用他们登录。然而，我得到这些错误，并且新用户在创建后没有立即登录，这让我很烦恼。这是我第一个使用Django和Redux的项目，因此任何帮助都将非常感谢。
Registration Error:

{detail: "User with this email already exists"}
detail: 
  "User with this email already exists"

这是我在网络选项卡上得到的错误。
Console Errors: POST http：//localhost：3000/api/users/register/400（Bad Request）
控制台上出现的错误
Login Errors
使用现有用户登录时出现的错误。我不知道这是否会影响功能，但我的首要任务是解决注册问题。

创建用户时没有问题，这表明问题在以下几行中。

serializer = UserSerializerWithToken(user, many=False)
return Response(serializer.data)

尝试打印序列化程序的内容，以找出可能的错误。
我不是Django的Maven，但觉得下面的内容需要再看一遍。
在UserSerializerWithToken中，您有

fields = ['id', '_id', 'username', 'email', 'name', 'isAdmin']

我假设这些是User对象上的字段。
在register函数中，您将创建一个具有“first_name”属性的User对象。如果first_name是对象上存在的属性，则您试图在UserSerializerWithToken中获取错误的字段“name”。
此外，检查您是否应该调用“RefreshToken”，因为如果用户是第一次注册，您将没有令牌。您可能应该在注册期间调用“AccessToken”。
希望这能帮上忙。
