MultipleObjectsReturned в /profile/ get() вернул более одного CustomUser - он вернул 2

Модель CustomUser хранит данные учетной записи пользователя. После входа в систему профиль конкретного пользователя должен быть получен с помощью токена, сгенерированного во время регистрации.

Я сделал phone_number в качестве первичного ключа и уникальный атрибут установлен в True. Мой код ведет себя правильно, когда есть только один пользователь, но >1 пользователь, данные всех существующих пользователей извлекаются, поэтому и появляется эта ошибка!

Вот структура модели

class CustomUser(AbstractUser):
first_name = models.CharField(null=True, blank=True, max_length= 50)
last_name = models.CharField(null=True, blank=True, max_length= 50)
username = models.CharField(null=True, blank=True, max_length= 12)
phone_number = models.CharField(primary_key=True, max_length= 10,unique=True)
dob = models.CharField(max_length=12, null=True, blank=True)
email = models.EmailField(null=True, blank=True)
address = models.CharField(max_length= 500,null=True, blank=True)
pincode = models.CharField(max_length=10, blank=True,null=True)
state = models.CharField(max_length= 256,null=True, blank=True)
district = models.CharField(max_length= 56,null=True, blank=True)
otp_verified = models.BooleanField(null=True,blank=True, default=False)
date_joined = models.DateTimeField(null=True,blank=True)
last_login = models.DateTimeField(null=True,blank=True)
loyality_level = models.IntegerField(null=True,blank=True)
loyality_points = models.IntegerField(null=True,blank=True)
gender = models.CharField(max_length= 2,null=True, blank=True)
user_type = models.CharField(max_length= 2,null=True, blank=True)

objects = MyUserManager()
search_fields = ("",)
USERNAME_FIELD = 'phone_number'

def __str__(self):
    return self.phone_number

@property
def token(self):
    return self._generate_jwt_token()

def _generate_jwt_token(self):
    return str(AccessToken.for_user(self))

Вот мое представление для получения профиля с помощью APIView

class ProfileView(APIView):
authentication_class = [JWTAuthentication]
permission_classes = [IsAuthenticated]
try:
    def get(self, request):
        print(request)
        user = model_to_dict(request.user)
        print(user)
        del user['password']
        return Response({"ok": True, "userData": user},status=200)
except Exception as e:
    print("::",e,"::")
