Hello, I'm trying to create a simple target group as below with pulumi java

var targetGroup = new TargetGroup("targetGroup", TargetGroupArgs.builder()
        .port(8080)
        .protocol("HTTP")
        .vpcId(vpc.id())
        .build());

But then I get the below error and I'm not sure how to resolve the same

Type                   Name            Status           Info

Facing similar issue. Tried to set "targetHealthStates" but unable to access it on "com.pulumi.aws.alb.TargetGroup" although given in the documentation.

is it resolved?

Not yet. It seems to be an internal issue in the SDK. You can have a look at this on the Pulumi Slack channel. https://pulumi-community.slack.com/archives/C01PF3E1B8V/p1700020885860759
