AWS Application Load Balancer cannot be created with HTTPS target group

[smsmithee]

What happened?

I'm trying to create an Application load balancer with a target group that sends to my servers via HTTPS; however, the Pulumi AWS SDK is throwing a null pointer exception due to TargetGroupTargetHealthState. My code does not set that field as it is not a valid element for an application load balancer. I tried setting it anyway and the Pulumi code errors saying that field cannot exist if the target group is using HTTPS

Here is the error I get when I do NOT include the targetGroupTargetHealthStatus (matches the example provided):

@smsmithee Sorry you ran into this! It looks like this is probably the other issue, so we'll treat this as a duplicate for now.
