Expected view UserDetails to be called with a URL keyword argument named "pk"

Question

models.py

class Customer(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    mobile = models.PositiveBigIntegerField(unique=True)

    def __str__(self) -> str:
        return self.user.username

serializers.py

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ['id', 'first_name', 'last_name', 'username', 'email']

    def __init__(self, *args, **kwargs):
        super(UserSerializer, self).__init__(*args, **kwargs)
        self.Meta.depth = 1

authentication.py

class JWTAuthentication(BaseAuthentication):
    def authenticate(self, request):
        print('authenticating')
        auth = get_authorization_header(request).split()
        print(auth)
        if auth and len(auth) == 2:
            token = auth[1].decode('utf-8')
            print('Decoded Token')
            print(token)
            id = decode_access_token(token)
            print(id)
            print(id)
            customer = models.Customer.objects.get(id=id)
            return (customer, None)
        raise exceptions.AuthenticationFailed('unauthenticated2')

def decode_access_token(token):
    try:
        payload = jwt.decode(token, 'access_secret', algorithms='HS256')
        print('accesstoken')
        print(payload)
        return payload['customer_id']
    except Exception as error :
        print('For token %s error detected %s', token, error)
        raise exceptions.AuthenticationFailed('unauthenticated1 ', error)

def create_access_token(id):
    print('AccessTokentime : ', current_time)
    print('access_token_expiry : ', access_token_expiry)
    return jwt.encode({
        'customer_id': id,
        'exp': access_token_expiry,
        'iat': current_time,
    }, 'access_secret', algorithm='HS256')

urls.py

    path('user/', UserDetails.as_view()),

views.py

class UserDetails(generics.RetrieveUpdateDestroyAPIView):
    queryset = models.User.objects.all()
    serializer_class = serializers.UserSerializer
    authentication_classes = [ JWTAuthentication ]

    def get_queryset(self):
        qs = super().get_queryset()
        print('self.request.user.id ', self.request.user.id)
        customerObj = models.Customer.objects.get(id=self.request.user.id)
        print('customerObj ', customerObj.user.id)
        return qs.get(id=customerObj.user.id)

I am using Postman to make a request to URL http://127.0.0.1:8000/api/user/ with header containing 'Authorization' key and 'Bearer ' value. As seen in the view.py snippet, I see logs as self.request.user.id 2 customerObj 4.
