我正在做一个项目，需要我上传一张图片。但是，当我试图上传一张，并张贴我妈得到上述错误。我不知道该怎么做了。
我已经尝试过使用FileUploadParser并创建类Base64ImageField了。请帮助。
模型

class UserProfile(models.Model):
    user = models.OneToOneField(User,on_delete=models.CASCADE, default=None, null=True)
    avatar = models.ImageField(upload_to='', blank=True, null=True)
    code = models.CharField(max_length=8, unique=True, default=unique_rand)
     emailVerified = models.NullBooleanField(null=True, default=None)
    facebookId = models.CharField( null=True,unique=True, default=None,max_length=255)
    googleId = models.CharField(null=True,unique=True,default=None,max_length=255)
    phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$')
    mobile = models.CharField(validators=[phone_regex, MinLengthValidator(10)], max_length=10, null=True, default=None)
    mobileVerified = models.NullBooleanField(null=True,default=None)
    status = models.BooleanField(default=False)
