为什么我在登录时得到 'ImageFieldFile' object has no attribute 'pk'？

Question

我正在使用 django-rest-auth 和 REST 框架 JWT Auth 在 Django-Rest_framework 中构建后端身份验证，当我登录时，我不断收到此错误。我做错了什么？

AttributeError at /api/auth/login/
'ImageFieldFile' object has no attribute 'pk'
Request Method: POST
Request URL:    http://127.0.0.1:8000/api/auth/login/
Django Version: 3.2.8
Exception Type: AttributeError
Exception Value:    
'ImageFieldFile' object has no attribute 'pk'
Exception Location: D:\Python Workspace\Rest_Gama\venv\lib\site-packages\rest_framework_jwt\utils.py, line 86, in jwt_create_payload
Python Executable:  D:\Python Workspace\Rest_Gama\venv\Scripts\python.exe
Python Version: 3.9.7

这是我的models.py

from django.contrib.auth.models import AbstractUser
from django.db import models


class CustomUser(AbstractUser):
    profile = models.ImageField(default='user_default_m.png', upload_to='profile/', blank=True)
    dob = models.DateField(auto_now=False, auto_now_add=False, blank=True)

这是我的serializers.py

from rest_auth.serializers import LoginSerializer as RestAuthLoginSerializer
from rest_framework import serializers

from users.models import CustomUser


class CustomUserDetailsSerializer(serializers.ModelSerializer):
    class Meta:
        model = CustomUser
        fields = ('pk', 'first_name', 'last_name', 'email', 'profile', 'dob', 'date_joined', 'last_login')
        read_only_fields = ('pk', 'email', 'date_joined', 'last_login')


class LoginSerializer(RestAuthLoginSerializer):
    username = None

尝试重新安装REST framework JWT Auth

pip install djangorestframework-jwt
