我认为这个问题是因为所有身份验证都尝试通过使用切片来订阅用户名我建议尝试以下操作

phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed.")
    phone_number = models.CharField(validators=[phone_regex], max_length=17, blank=True) # validators should be a list
