Pulumi aws.alb.LoadBalancer configuration for access_logs is not enabling the logs attribute for load balancer

[pk-hugo]

Describe what happened

When using the pulumi python for creating load balancer we are not able to configure the access_logs for the alb if we have a prefix. It only works if we don't add any prefix.

The ideal behaviour should be that the alb should create the directory for prefix by itself and the configuration should work. This is the case if we do it manually. But with pulumi this is not working like that and won't throw any error as well.

The preview shows the change in access_logs and pulumi up won't give any error. But the access_logs are never enabled for the load balancer.

Sample program

This can be reproduced with the same code given in the documentation as well. https://www.pulumi.com/registry/packages/aws/api-docs/alb/loadbalancer/

import pulumi
import pulumi_aws as aws

test = aws.lb.LoadBalancer("test",
    name="test-lb-tf",
    internal=False,
    load_balancer_type="application",
    security_groups=[lb_sg["id"]],
    subnets=[subnet["id"] for subnet in public],
    enable_deletion_protection=True,
    access_logs={
        "bucket": lb_logs["id"],
        "prefix": "test-lb",
        "enabled": True,
    },
    tags={
        "Environment": "production",
    })

Hi @pk-hugo, would you care to try again? Specifying a prefix is working fine for me. I'm using Python as well:

import pulumi_aws as aws

aws.lb.LoadBalancer(
    "test"
    access_logs={
        "bucket": <bucket name>,
        "enabled": True,
        "prefix": <prefix>,
    },
    internal=True,
    security_groups=[<security_group_id>],
    subnets=[<subnets>],
)

I'm using Pulumi 3.135.1 and Pulumi-AWS 6.54.2.
