aws-alb-lambda: Does not allow ApplicationLoadBalancerProps

[darrenflannerypoppulo]

Describe the bug

On the aws-alb-lambda it says you can specify ApplicationLoadBalancerProps, but says the following This cannot specify a VPC, it will use the VPC in existingVpc or the VPC created by the construct. .

I tried to all ApplicationLoadBalancerProps without a vpc so I can specify what subnets I want the ALB to be created in, but I get an error, saying 'vpc' is a required field.

When I add a vpc, the same as the existing_vpc property. I also get an error: Specify any existing VPC at the construct level, not within loadBalancerProps.

My Code:

alb_to_lambda = AlbToLambda(
            self,
            f"{STACK_PREFIX}{self.stack_config.function_name}AlbToLambda",
            lambda_function_props=FunctionProps(
                runtime=Runtime.PYTHON_3_9,
                handler=self.stack_config.function_handler,
                code=get_lambda_code(self.stack_config.lambda_code_path),
                function_name=f"{STACK_PREFIX}{self.stack_config.function_name}",
                description=f"{STACK_PREFIX}{self.stack_config.function_description}",
                log_retention=RetentionDays.FIVE_DAYS,
                timeout=Duration.seconds(30),
                environment=self.stack_config.environment,
                dead_letter_queue=dlq,
                memory_size=self.stack_config.memory_size,
            ),
            target_props=elbv2.ApplicationTargetGroupProps(
                target_group_name=f"{STACK_PREFIX}{self.stack_config.function_name}TG",
                health_check=elbv2.HealthCheck(
                    path="/healthcheck", interval=Duration.minutes(5), enabled=True
                ),
            ),
            existing_vpc=vpc,
            listener_props=elbv2.BaseApplicationListenerProps(
                certificates=[certificate],
            ),
            load_balancer_props=elbv2.ApplicationLoadBalancerProps(
                vpc_subnets=subnets,
            ),
            public_api=False,
        )

Expected Behavior

I can add ApplicationLoadBalancerProps to AlbToLambda construct

Current Behavior

I cannot add ApplicationLoadBalancerProps to AlbToLambda construct without getting an error

Try to deploy an AlbToLambda construct using ApplicationLoadBalancerProps as a property
