DRF auth_token "non_field_errors": [ "无法使用提供的凭据登录" ] 使用自定义用户模型

如何解决DRF auth_token "non_field_errors": [ "无法使用提供的凭据登录" ] 使用自定义用户模型

我正在尝试使用现有数据库创建一个 rest api。我也在使用 drf 令牌身份验证并为所有现有用户创建了令牌。当我尝试输入我的用户名和密码以从我的获取验证令牌视图中获取我的令牌时，我收到以下错误：

 "non_field_errors": [
        "Unable to log in with provided credentials."
    ]

我的代码如下：
